SpecProof MCP server

Which MCP servers are SpecProof's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameai.specproof/specproof-mcpverified in the MCP registry

The registry name sits under specproof.ai. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-23 the server answered initialize and tools/list without a sign-in. First answer in 191 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "search 3GPP, IETF and MPEG specifications by meaning", the likely first call is semantic_search.
  • Parameters are untyped or undescribed in 15 of 17 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • get_spec_references

    Get all specifications referenced by a given spec. Args: spec_number: Specification number (e.g., "23.501", "26.230") reference_type: Filter by type - "normative", "informative", "inline" (optional)

  • get_spec_dependents

    Get all specifications that reference a given spec (reverse lookup). Args: spec_number: Specification number to find dependents of max_results: Maximum results (default: 50)

  • get_relationship_graph

    Get a relationship graph centered on a specification, expanding N hops. Returns JSON with nodes and edges suitable for graph visualization. Each node includes title, series, working group, and reference counts. Each edge includes source…

  • get_spec_metadata

    Get enriched metadata for specifications with filtering. Args: spec_number: Filter by spec number (partial match) series: Filter by series (e.g., "26" for 26.xxx codecs) working_group: Filter by working group (e.g., "SA4") doc_class…

  • get_most_referenced_specs

    Get the most referenced (most important) specifications ranked by incoming reference count. Args: doc_type: Filter by "3gpp" or "ietf" series: Filter by series number limit: Maximum results (default: 20)

  • get_series_overview

    Get an overview of all specification series with document counts, reference statistics, and working group assignments.

  • search_specifications

    Search across 3GPP, IETF, and Multimedia specification documents using full-text search. Args: query: Search query terms (required) doc_type: Filter by document type - "3gpp", "ietf", or "mpeg" (optional) spec_number: Filter by…

  • semantic_search

    Perform semantic search using vector embeddings with FAISS acceleration. Args: query: Natural language search query (required) max_results: Maximum number of results to return (default: 5, max: 20) similarity_threshold: Minimum similarity…

  • get_document_content

    Get specific content from a specification document. Args: filename: Document filename (required) page_range: Page range like "10-15" or single page "20" (optional) section: Section title filter (optional)

  • list_documents

    List available specification documents. Args: doc_type: Filter by document type - "3gpp", "ietf", or "mpeg" (optional) search_pattern: Search pattern for spec number or title (optional) limit: Maximum number of results (default: 20, max…

  • get_requirements

    List normative requirements (RFC 2119 / BCP 14 "shall/should/may" statements) extracted from specifications, each cited back to its source clause. Args: spec_number: Filter by spec number, e.g. "23.501" or "RFC 9110" (optional)…

  • generate_tests

    Generate a cited, runnable conformance test that verifies one normative requirement. The test is grounded in the requirement sentence plus its surrounding clause from the corpus, and every test cites the spec, section and page it…

  • diff_spec_versions

    Diff two versions of a specification at the NORMATIVE level: which requirements were added, removed, or reworded. Not a textual diff — a clause that merely moved page or was recased counts as unchanged. Args: spec_base: Spec identity…

  • get_schema_definitions

    Look up formal, machine-checkable structure defined in the specifications: ASN.1 types (3GPP RRC/NAS message grammars) and JSON Schema / OpenAPI models (5G Service Based Interfaces). Prefer this over prose search when the question is…

  • get_rfc_lineage

    An RFC's revision history. RFCs are immutable — an RFC is never revised, it is obsoleted or updated by a *different* RFC — so this Obsoletes/Updates graph, not a version diff, IS its change history. Use it to find out whether an RFC you…

  • build_cross_spec_suite

    Assemble the normative requirements for one procedure across a spec AND the specs it normatively references — a procedure like registration or handover is never described in a single document. Returns a cited suite plan; feed the…

  • get_database_stats

    Get comprehensive database and system statistics.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "specproof-mcp": {
      "type": "http",
      "url": "https://mcp.specproof.ai/"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http specproof https://mcp.specproof.ai/

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.specproof.ai/ as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
