Endpoint Security77
Transport & Reachability100
Schema Quality & AI Usability71
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 481 tokens (~96/item across 5 items; 5 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail

  • Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass

Install

How do I install the RCO-A2A - Regulatory Compliance Objects MCP server?

RCO-A2A - Regulatory Compliance Objects is a hosted endpoint at https://mcp.rco-a2a.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

MCP tools · 5 exposed · ~393 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

publish_record ~174

Publish a signed Regulatory Compliance Object to the partner rail (rco-a2a-cpg.ai). The ONLY write path in the suite, and it accepts only what already verifies: the record must be schema-valid RCO v1.3, its issuer must be a cpg-rail issuer active in the signed consortium registry, its verification_url must equal that issuer's registry JWKS URL, its detached JWS must verify against that JWKS, and its record_id (and any supersession) must be consistent. GSC never authors a partner record and never holds a partner private key: GSC verifies, receipts to Azure Confidential Ledger, and serves. A submitted record is never modified. Idempotent: republishing a byte-identical record returns the same receipt. Typed errors only.

resolve_compliance ~99

Return the current signed Regulatory Compliance Object for an object in a jurisdiction. Deterministic. Inside the resolved universe (SPEC v1.2 pairs.json + the jurisdiction doors' own objects) an unknown object returns a pre-resolved, signed CPG-404 record; outside it the typed error record_not_found is returned - nothing is signed at request time. Never narrative.

RCO-A2A - Regulatory Compliance Objects scores 79 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the RCO-A2A - Regulatory Compliance Objects MCP server expose?

RCO-A2A - Regulatory Compliance Objects exposes 5 tools: resolve_compliance, get_record, list_rule_sets, list_issuers, publish_record. Their descriptions and schemas cost roughly 393 tokens of context every time the server is loaded.

Does the RCO-A2A - Regulatory Compliance Objects MCP server require authentication?

No. We connected to RCO-A2A - Regulatory Compliance Objects without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the RCO-A2A - Regulatory Compliance Objects MCP server still maintained?

RCO-A2A - Regulatory Compliance Objects is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
