Tools

• build_supplier_request_package

  Build a synchronous, deterministic supplier request package from the requirement the caller already holds. The package follows the open a2a2p supplier profile and its versioned output schema at https://a2a2p.com/schema/supplier-package, preserves provenance, carries quote-stage screening, and names every quote-critical gap instead of inventing values. If no package can be built, MCP and REST share the a2a2p.supplier-package-rejection contract: a closed reason_code, exact vocabulary version, and deterministic next_action only where repair is sufficient. A purpose_required rejection includes an a2a2p.argument-repair operation that preserves the caller's existing arguments, requires the caller's own purpose statement, and forbids inference. An explicit specification.assembly with two or more parts returns decomposition_required and no package; one package represents one fabricated part. This is a stateless data transformation only: it stores no requirement, contacts no supplier or provider, requests no external quote, and creates no order, payment, or fabrication authority.

  shallow
• check_quote_job

  Check an asynchronous provider-estimate job created by request_provider_estimate. Terminal statuses: completed, degraded, refused. An unknown read returns reason_code=unknown_or_not_yet_visible. Retry with backoff only when the id came from an authoritative admitted response; never infer an id after a rejected admission.

  shallow
• check_request_status

  Check the status of a previously submitted physical-solution request. Returns the current status and, once ready, the full resolution report. For an immutable revision, it also returns its persisted deterministic readiness_progress comparison.

  shallow
• derive_rectangular_beam_section

  Derive one proposal-only prismatic rectangular beam height from a caller-declared purpose, supported idealized load model, fixed width, explicit elastic modulus, and at least one requester acceptance criterion. The operation solves closed-form equations, rounds upward to the caller's manufacturing increment, and re-runs the canonical bounded evaluator. It performs no general optimization, material selection, network call, supplier contact, persistence, purchase, or fabrication and grants no engineering or physical authority.

  shallow
• explore_rectangular_beam_sections

  Evaluate 2 to 12 caller-declared rectangular beam widths through the canonical bounded height derivation, then return every proposal and the exact non-dominated frontier for minimizing section height and idealized prismatic material volume. Width order is normalized; duplicates fail closed. The operation never invents a width, assigns an aggregate score, selects a candidate, estimates material cost, verifies manufacturing or omitted failure modes, calls an external system, or grants engineering, purchase, or fabrication authority.

  shallow
• get_supply_options

  Instant, synchronous pricing and lead time for a physical requirement — nothing is submitted or stored. Returns a deterministic parametric estimate (source="estimate", pricing_kind="model_estimate", clearly labeled, never presented as a quote). The protocol separately labels provider_estimate and provider_quote; public provider routing is not active. An explicit specification.assembly with two or more parts returns decomposition_required before file inspection or pricing; submit each fabricated part separately. Covers CNC machining, sheet metal, 3D printing, casting, injection molding, and extrusion. ATTACH AN STL in specification.design_files and a2a2p measures the mesh directly — true volume, surface area, bounding box — which replaces guesswork with measurement and returns manufacturability findings only geometry reveals. Otherwise supply intent.geometric_envelope (bounding box in mm), quantity, and material. Use this to answer "what will this cost and how long will it take?" inside a single session, before committing to a full resolution report.

  shallow
• plan_material_evidence_promotion

  Plan the evidence needed to transform a validated material source observation into a future material-property-evidence input. Deterministic and stateless: it compares exact property, material-state, orientation, temperature, and process context; binds source, target, and planner digests; and names conflicts plus missing method, uncertainty, freshness, and excerpt evidence. It never promotes the observation, creates simulation input, calls a model or solver, contacts a supplier/provider, or grants engineering, order, payment, or fabrication authority.

  shallow
• prepare_derived_beam_simulation

  Compile one exact replay-verified rectangular-beam derivation into a prepared bounded simulation study. The caller must supply the original derivation input and receipt, its exact validation receipt, simulation-eligible source-bound material evidence matching the modulus, an objective, source freshness, and a physical validation plan. The compiler replays first, derives a stable candidate ID, repeats deterministic review, preserves requester criteria as hard gates, and publishes omitted failure modes. It never chooses material or objective, verifies physical truth, runs a solver, stores data, contacts a supplier, or grants physical authority.

  shallow
• prepare_domain_solutioning_case

  Prepare a synchronous, deterministic, privacy-minimized engineering case for a compatible domain-intelligence system. Use it when intake_classification is capability_concept or assembly_or_system and mechanism selection or decomposition is required. The case preserves requester facts, deterministic evidence, screening state, unknowns, and a versioned candidate-output contract while removing design-file URLs, bytes, contact fields, and callback routes. This operation does not call deb8stack or any model, choose a mechanism, validate a proposal, store a request, contact a supplier, or grant quote, order, payment, or fabrication authority.

  shallow
• prepare_reviewed_beam_simulation

  Compile one caller-selected domain-solutioning candidate into a prepared bounded beam simulation study after repeating deterministic engineering review. The requirement must explicitly state the supported load model, geometry, load, and elastic modulus; the caller must state the objective, source freshness, and physical validation plan. Optional material_property_evidence content-addresses an exact engineering datasheet or measurement with material state, applicability, method, and uncertainty; its value must match the requirement. Semantic placeholders such as unknown, unspecified, n/a, or tbd cannot make material state or applicability simulation-eligible. Computed-crystal evidence remains screening/reference-only because this scalar product model cannot preserve its tensor, orientation, grade, condition, or product-form boundary. Requester limits become hard constraints. It never verifies a source claim, selects a candidate, invents physics, runs a solver, stores data, contacts a supplier, or grants physical authority.

  shallow
• prepare_simulation_study

  Prepare a deterministic, side-effect-free simulation study for existing a2a2p domain-solutioning candidate IDs. It records exact quantities, units, closed-kind source snapshots with staleness intervals, hard constraints, solver/model/settings provenance, assumptions, validity domain, and a physical validation plan. It runs no solver, chooses no candidate, stores nothing, and grants no physical authority.

  shallow
• render_supplier_email_binding

  Render the caller's requirement as a reviewable RFC 5322 supplier-email draft after rebuilding its canonical supplier package and repeating quote-stage screening. Only an allow verdict renders. The operation validates one explicit recipient and an accountable sender-domain envelope, but cannot verify SPF, DKIM, or DMARC and therefore returns sendable=false. An explicit specification.assembly with two or more parts returns decomposition_required before file inspection or rendering. It is a stateless artifact transformation only: it stores nothing, sends nothing, contacts no supplier or provider, and grants no quote, order, payment, or fabrication authority.

  shallow
• request_physical_solution

  Submit a physical-world requirement (a part, product, device, or capability that must exist in the physical world). a2a2p resolves it and returns a RESOLUTION REPORT: a recommended path (best existing commercial solution vs. custom fabrication), pricing, tradeoffs, a delivery plan with contingencies and expedite options, and a business case when business context is provided. Response is asynchronous: you receive a request_id immediately (with an instant spec_review); a draft report is typically ready within a few minutes, the human-reviewed final within 24 hours. Poll check_request_status to retrieve it. ENTRY MODES — arrive with what you have: • fully_specified: provide 'specification' (part_type, material, process, dimensions, tolerance_class, design_files). Go straight to resolution report. • intent_only: provide 'intent' (purpose, environment, functional_requirements, quantity, timeline, priority). a2a2p recommends 2-3 specification options with tradeoffs. • partial: provide what you know in either layer; a2a2p fills the gaps. Layer 1 (intent) describes the PROBLEM. Layer 2 (specification) describes the SOLUTION. At minimum, provide 'requirement' (legacy) or 'intent.purpose' (structured) — one line describing what you need. Use 'rejected_alternatives' to record options already ruled out.

  shallow
• request_provider_estimate

  Submit a requirement for an asynchronous REAL-PROVIDER estimate (pricing_kind="provider_estimate") without holding the connection open. Returns a quote_job_id in milliseconds; the provider call runs out-of-band. Additive processes with an STL design file only, for now. The requirement is screened before storage and the exact file bytes are screened again before any provider contact; a deny refuses the submission. Every admission result is machine-readable. Rejections carry a stable closed-set reason_code, retry boundary, required input, and deterministic next_action; admitted responses carry the same versioned admission contract. An explicit specification.assembly with two or more parts is rejected before job creation or provider contact and must be decomposed first. Estimate only — never a quote, order, payment, or fabrication commitment. Poll with check_quote_job until a terminal status: completed (provider figure), degraded (deterministic model estimate with the provider's absence explained), or refused (screening).

  shallow
• review_specification

  Instant, synchronous engineering review of a physical requirement — nothing is submitted or stored. Deterministic checks: material identification with handbook-typical properties (density, stiffness, yield, service temperature), explicit rectangular beam deflection and nominal stress with requester-defined acceptance criteria, material/process compatibility, tolerance-vs-process reality, quantity economics (e.g. tooling amortization), environment fit (UV, saltwater, food contact, temperature, medical), flexibility fit, post-processing validity, design-file format fit, and specification completeness. Returns findings ranked blocker/warning/info, two readiness scores, and a deterministic clarification_plan: compact next_fields, visible remaining_fields, optional CAD accelerators, an intent-only resolution handoff, next_call with the recommended exact MCP/REST continuation, and continuation_options for every operation explicitly eligible from a complete specification. Examples are shapes, never invented defaults. For a decomposed design, send specification.assembly with parts and interfaces: a2a2p then checks galvanic pairing and interface fit across parts, which a single-part review cannot, and prices each part separately. Two or more explicitly declared parts always classify as assembly_or_system and can never become quote_ready as one part, regardless of purpose wording or top-level part fields. Undeclared interfaces are unchecked — nothing is inferred. CHECK intake_classification first. a2a2p reviews one manufacturable part at a time; a request naming a behaviour rather than an object ("a device that detects and removes debris") is classified capability_concept and redirected to decomposition, because no material or tolerance can be derived from it. The classification is advisory, never blocks, and defers to any supplied specification. READ resolution_readiness, not quote_readiness, while you are still answering questions. quote_readiness is supplier-facing and stays capped by material/process/dimensions/tolerance that a2a2p derives for you, so it cannot reach quote_ready from intent alone however much you supply. resolution_readiness measures only what the requester owns and reaches ready_to_resolve once you have supplied enough to derive a specification — which is not a supplier quote. completeness.awaiting_requester and completeness.derivable_by_resolution say which fields are whose. Accepts the same input as request_physical_solution (structured intent/specification or legacy flat fields). For intent_only, complete requester context leads to submit_for_specification_resolution; for a supplied specification, apply only facts you know, re-review until quote_ready, then submit if a durable resolution is useful.

  shallow
• revise_requirement

  Create a new, immutable revision of a prior request by applying only the fields you learned since the first submission. Use this after review_specification returns a clarification_plan: provide the original request_id plus the patch (for example intent.geometric_envelope or specification.material). The original is preserved; the revision receives a new request_id, a fresh spec_review, a revision_of link, and a deterministic readiness_progress comparison against its immediate predecessor. Provide idempotency_key when retrying the same patch so a network retry returns the same revision instead of creating another.

  shallow
• run_bounded_simulation_study

  Execute and validate a prepared simulation study through a2a2p's bounded closed-form rectangular-beam adapter. The adapter accepts only explicit load, span, section width/height, elastic modulus, exact support conditions, and supported output quantities; missing, extra, mismatched, or unsupported settings fail the affected experiment closed. It returns provenance-bound predictions and the existing hard-constraint/Pareto validation in one stateless call. It is not FEA, physical measurement, engineering validation, candidate selection, supplier contact, or fabrication authority.

  shallow
• translate_materials_project_elasticity

  Translate one bounded, caller-supplied Materials Project elasticity API response projection into source-bound computed-crystal reference evidence. Optional retrieval metadata binds the raw upstream bytes separately and records that an allowlisted projection changed the representation. The adapter verifies response shape, one exact material ID, non-deprecated successful state, modulus bounds, Poisson consistency, source versions, and record license; derives an isotropic VRH Young's modulus deterministically; and preserves warnings. It performs no network call, does not verify Materials Project origin, and grants no engineering-product, simulation-input, supplier, order, payment, or fabrication authority.

  shallow
• upload_design_file

  Turn local manufacturing file bytes into the temporary HTTPS reference used by specification.design_files. This is a bounded intake operation, not a request, provider call, quote, order, payment, or fabrication action. Common RFC 4648 transport forms are normalized, then decoded bytes are recognized by signature, checked against the declared format, screened before storage, retained for one hour, and never included in telemetry. Supported roles include geometry (STL/STEP) and drawings (DXF/PDF). The 2 MiB MCP ceiling is transport-specific; use POST /api/upload with purpose=manufacturing_design_file for files up to 8 MiB. Pass the returned file_reference object unchanged in specification.design_files on the next call.

  shallow
• validate_domain_solutioning_result

  Validate a candidate result returned under the a2a2p domain-solutioning contract. The exact output of prepare_domain_solutioning_case is a prerequisite; malformed or non-prepared cases return a versioned machine-readable recovery workflow without weakening case-shape or digest checks. The operation verifies the source-case digest and provenance shape, rejects authority promotion and intent or design-file mutation, re-screens every candidate at quote stage, and runs the deterministic engineering review only after screening allows it. It stores nothing, calls no model or supplier, applies no patch, and grants no provider, quote, order, payment, or fabrication authority.

  shallow
• validate_material_property_evidence

  Validate and content-bind one caller-supplied material-property evidence envelope before attaching it to a compatible preliminary simulation. The receipt separates shape/content identity from source truth, material identity, uncertainty verification, design allowable, engineering validation, and physical authority. Computed-crystal evidence remains valid reference data but ineligible for the scalar engineering-product beam path. The operation calls no model or solver, stores nothing, contacts nobody, and creates no physical evidence, order, payment, or fabrication authority.

  shallow
• validate_rectangular_beam_section_derivation

  Recompute a bounded rectangular beam-section derivation from the exact declared input and reject any mutation of the candidate, digests, assumptions, claim limits, external-effects boundary, authority boundary, or carried screening receipt. Success proves deterministic replay and content identity only; it does not make the candidate simulation-eligible, physically true, supplier-ready, approved, purchased, or fabrication-authorized.

  shallow
• validate_rectangular_beam_section_design_space

  Recompute a bounded finite rectangular-beam design space from the exact caller-held input and reject any mutation of an embedded derivation, Pareto disposition, digest, claim limit, external-effect boundary, authority boundary, or carried screening receipt. Success proves deterministic replay and content identity only. It never selects or promotes a candidate, estimates cost, calls an external system, or grants simulation, supplier, purchase, or fabrication eligibility.

  shallow
• validate_simulation_study_result

  Validate a prepared a2a2p simulation-study result. Masked timeout, non-convergence, boundary, unit, provenance, unsupported-model, and solver failures fail closed. Hard constraints gate eligibility; distinct objective values remain visible; Pareto dispositions are canonical and order-independent. It runs no solver, applies no candidate, stores nothing, and grants no physical authority.
