1430 servers, 5735 tools — a rough corpus-diversity category (see methodology), not a rigorous similarity match. 7 scored, 5728 not yet tested — coverage here means the deep-tier probe, not the corpus-wide shallow score.
Ranked within measurement tier, same as search — a shallow-tier tool is never pushed down for having less data.
- a2a_call_agentio.github.Tim-Projekt/agent-routershallow100.0
Call any public A2A-compatible agent directly by its endpoint URL. Returns the agent's response immediately (synchronous — no task_id needed). Get agent_url values from discover_agents (look for ENDPOINT in results). Works with any agent on a2aregistry.org or any A2A JSON-RPC endpoint. Free, no login required. Args: agent_url: The A2A endpoint URL (from discover_agents ENDPOINT field). message: The message or task to send to the agent. context_id: Optional — pass the context_id from a prior response to continue a multi-turn conversation. timeout_seconds: Seconds to wait for a response (default 30, max 120).
- abi_fetchio.github.zvmzaretsky/onchain-decodeshallow100.0
PAID $0.002 (x402, USDC on Base). Fetch the verified ABI + metadata for a contract. Give {address, chain}; get the ABI JSON, verification status/source (Sourcify or Blockscout), the callable function/event signatures, and full proxy-implementation resolution (EIP-1967/1822/OZ-legacy/beacon) — returning the implementation's ABI when it's a proxy. Without payment returns the x402 challenge; pass x_payment to settle.
- accept_quotestudio.agoria/registryshallow100.0
Choose a business's quote. This creates a real order at that business and declines the others. If that business protects payments, the reply carries a payment link where the money is held by Agoria until the customer confirms they got the work — hand that link to the customer.
- accountio.github.YS-projectcalc/agent-cold-emailshallow100.0
Account overview: brand, plan, status, billingState, activationState, resource counts, usageCents, quota, deliverability (loop state: paused/throttled mailboxes, burning domains, auto-replacements, recentActions[]), and teardown (reclaim summary once canceled, else null). Billing is per-provisioned-mailbox: $49 platform + $10 x live provisioned mailboxes, minimum 5 ($99); the billed quantity tracks the real provisioned count (deprovision lowers it). activationState is the HONEST send state — trust it over 'sent' counts: 'active' = real sending live; 'pending_provisioning' = paid but infrastructure still being armed, sends shown are sandbox previews that DON'T leave; 'capacity_pending' = provisioning held at a spend/plan-slot limit; 'screening_hold' = account under review; 'sandbox' = demo/free. Use metrics for counts, infrastructure_status for per-mailbox health.
- accountsh.graded/graded-x402shallow100.0
Your balance, totals, limits, and recent calls. Requires Authorization: Bearer <gwk_ key>.
- account_statsio.github.wilmendezofficial/postarishallow100.0

- account_statuscom.zylalabs/api-hubshallow100.0
Check the current user's account status, billing, and usage. Returns plan info, API call count, the amount consumed this billing cycle in USD (amount_consumed_this_cycle_usd), whether a credit card is on file, and any failed/pending payments. Use this to diagnose why API calls are blocked (missing card or failed payment). Requires the user's API key in the Authorization header.
- account.agendaco.getrefine/refineshallow100.0
Get upcoming interviews and action items
- aci55com.danielsdesignstudio/mirror-ai-citabilityshallow100.0
Look up The ACI 55 — Daniels AI's published benchmark of 55 leading consumer brands measured by AI Citability Score (ACS), the standard for Brand Discovery Intelligence (BDI) across answer engines (AEO), generative AI (GEO), and search (SEO). Presented by category as a banded dataset (bands: Above Average / Average / Below Average / Excellent) — NOT a 1-to-55 ranking. Call with NO arguments to get the complete dataset: 11 categories, each brand with brand, category, ACS band, ACS, AEO, GEO, and SEO. Call with a `brand` name for that brand's ACI 55 standing — its band, ACS, sub-scores, category, priority gap, and summary. This is the published, citable standard (August 2026 Edition · Rubric V3.0, CC BY 4.0). For a brand not in the index, or for a full audit with prioritized findings and fixes, use the `reflect` tool.
- ack_messageio.github.YS-projectcalc/agent-cold-emailshallow100.0
Acknowledge a message by id (from list_messages or infrastructure_status's messages[]) — sets it read so it stops surfacing as unacked. THIS IS THE ONLY THING THAT SETS readAt: reading or listing messages never marks them, so a message stays unacked until you call this explicitly. Idempotent: acking an already-acked id returns success with no second effect, never an error. 404 if the id doesn't exist for this tenant.
- acquire_domainrun.domani/domanishallow100.0
Ask domani to acquire a specific taken, unlisted domain on your behalf. Agents source the owner via RDAP, reach out anonymously, and negotiate - commission-only, no upfront fee. Owner interest opens an anonymous negotiation you can accept/counter. Note: many owners are unreachable (GDPR-redacted WHOIS). Requires deals:write scope.
- action-receiptai.intuitek.the-stall/the-stallshallow100.0

- add_knowledgeorg.singchat/singchatshallow100.0
Train the AI agent by adding a knowledge source. type='url' crawls a website (up to 50 pages); type='qa' stores a single question/answer pair. Ingestion is asynchronous, the source starts as PENDING; poll `list_knowledge` for READY status.
- add_leads_to_campaigncom.persuadioai/mcpshallow100.0
Move leads this account owns into a campaign this account owns, by explicit id. Updates membership only — sends nothing. Opted-out and suppressed leads are REJECTED with per-lead skip reasons even when listed explicitly; leads already in the target are deduplicated; the response includes the campaign's final lead count read back from the database. To pick the audience by filter instead of by id, use select_and_attach_leads (same attach semantics, driven by search_leads filters). If the target campaign was already reviewed, its earlier approval is stale (the launch step recounts recipients and refuses a token approved for a smaller audience), so a fresh review_campaign_readiness is required before launching.
- add_mail_rulerun.domani/domanishallow100.0
Add an inbound filtering rule to a mailbox. If a message matches (by from/to/subject/body), the action runs: drop, mark_read, forward (to action_arg), webhook_only (skip forward-to), or label (with action_arg).

- addDomaindev.primitive/emailshallow100.0
Claim a new domain and receive the DNS records to publish. Returns dns_records with the exact records to add. If the domain has an mx_conflict (existing mail provider), re-call with confirmed: true to proceed. After publishing DNS records, call verifyDomain to complete setup.
- AddPortfolioLotio.github.daniel3303/equiblesshallow100.0
Record one purchase or sale in the USER's own portfolio as a lot: what was bought or sold, how much of it, at what price per share, and when. Ask the user for anything you are not sure of. Never guess a price or a date, and never invent a holding from something they merely mentioned. For a stock, pass its ticker. For an option, pass BOTH the underlying ticker and the OCC symbol in optionContract (e.g. O:AAPL260724C00110000). The contract's expiration, strike, type and contract size are read from the live options data, so an unknown or expired symbol is rejected rather than stored. GetOptionExpirations and GetOptionChain find the symbol. quantity is SIGNED: positive for shares bought or contracts bought, negative for a short sale or a written (sold-to-open) option. costPerUnit is always a positive price per share, what was paid for a long and what was received for a short, because the direction is carried by the sign of the quantity alone. For an option that is the premium per share, not per contract: 2 contracts at $3.20 means quantity 2 and costPerUnit 3.20. Retrying the identical call is safe: within a few minutes it returns the lot already recorded instead of adding a second one.
- address_screencom.professorsausages/sausage-trustshallow100.0
Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
- address_validatecom.blixtworks.www/toolsshallow100.0
Validate an EVM address and detect whether it is a contract. POST {"address": "0x...", "chain": "base"} -> checksum form and account type. Costs $0.005 in USDC on Base — pass paymentTx or payerAddress to pay (call how_to_pay for details).
- address-intelai.intuitek.the-stall/the-stallshallow100.0
PAID MCP TOOL — $0.050 USDC per successful call via native x402. Discovery is free. On-chain intelligence for any Base network wallet. Classifies EOA vs contract, profiles USDC transfer activity over a configurable block window, scores payer diversity (distinct counterparties / total transfers, 0–100), detects sybil vanity-lookalike address clusters (same first-4 + last-4 hex chars), identifies x402 facilitator SKIM legs (same-block receive+re-send), and assigns a risk label (ORGANIC / ORGANIC_LIKELY / SEEDER_PATTERN / FACILITATOR_SKIM / SYBIL_CLUSTER / FRESH_WALLET / INACTIVE). Three modes: quick (address type+balance+24h USDC summary), standard (+full transfer history+diversity score), deep (+sybil/SKIM detection+risk label). Zero data COGS — Base public RPC only.
