Owner verification
Not yet verified. Verifying proves you control this server and is free, permanently — it never changes a published score.
Start verification →Tools
- coldstate_batch_searchshallow
Run several knowledge-base queries in one call against a single consistent kb_snapshot. Returns each query with its ranked results — efficient and snapshot-consistent across the whole batch.
- coldstate_browse_documentsshallow
Browse documents in a ColdState index. Indexes are zero-knowledge, so each document is returned as your ref_id plus its state classification and E-score — no stored text. Map ref_id back to your own content.
- coldstate_capabilitiesshallow
Machine-readable manifest of this server: available tools, knowledge domains, current kb_snapshot, determinism guarantees, and limits. Call this first to self-configure.
- coldstate_citeshallow
Get a canonical, reproducible citation for a knowledge entry by id (title, domain, source, content_hash, kb_snapshot). Cite a fact so it can be re-verified later with coldstate_verify.
- coldstate_domainsshallow
List all available knowledge domains in ColdState's global knowledge base with entry counts.
- coldstate_explainshallow
Explain why a specific document ranked for a query. Returns a per-term relevance breakdown and an overall match summary — deterministic and reproducible.
- coldstate_fetchshallow
Fetch a single knowledge-base entry verbatim by its stable id (e.g. "eng_000229f438f7cebd"). Deterministic retrieval — returns the full record plus a content_hash and kb_snapshot for reproducible citation.
- coldstate_isomorphshallow
Cross-domain structural analog: given a knowledge entry id, find its closest structural twin in each OTHER domain ("same structure, different domain"). Deterministic. Use coldstate_resolve to turn a name into an id first.
- coldstate_list_indexesshallow
List all your ColdState indexes with their status, mode, document count, and domain preset.
- coldstate_relatedshallow
Find knowledge entries deterministically related to a given entry id via ColdState's concept-cluster graph. Returns same-cluster and neighboring-cluster entries, each tagged with its relation and a cross_domain flag. Same id ⇒ same neighbors.
- coldstate_resolveshallow
Resolve a name, alias, or surface form to its canonical ColdState knowledge entry (id + title). Deterministic: an exact title match wins, else the top relevance-Ψ entry. Returns the canonical entry plus alternatives. Use the returned id with coldstate_fetch / coldstate_related.
- coldstate_searchshallow
Search a ColdState index by collection name or index ID. Returns ranked results with Ψ scores and state classification (CRYSTALLINE/FLUID/REACTIVE/DECOHERENT). Provide exactly one of `collection` or `index_id`.
- coldstate_search_globalshallow
Search ColdState's global knowledge base (48.4M+ entries across 35 domains including SCIENCE, MEDICINE, TECHNOLOGY, HISTORY, etc). Returns deterministically ranked results with Ψ relevance scores and a state classification. Optionally filter by domain.
- coldstate_snapshotshallow
Get the current knowledge-base snapshot/version id. Pin this kb_snapshot for reproducibility: the same query against the same kb_snapshot returns identical results.
- coldstate_statsshallow
Deterministic statistics. With a `query`: total matches + state distribution of the top results. Without: global knowledge-base stats (entry count, domains, snapshot).
- coldstate_verifyshallow
Verify a previously-cited knowledge fact is unchanged. Provide the entry id and the content_hash you stored earlier; returns whether it still matches the current knowledge base. The trust primitive for AI-to-AI fact-checking.

Tool count and median score across every tool in this server’s corpus — honest in a way a single cherry-picked tool’s badge wouldn’t be.
