acta-mcp
Enables contributing, challenging, discovering, verifying, and querying contestable public records from AI coding tools via MCP.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
acta_contributeSubmit a typed contribution to the Acta public record. Questions have no evidence burden. Factual claims require a source or reasoning. Opinion/hypothesis claims require uncertainty. Predictions require resolution criteria, date, source, and rule.
acta_respondSubmit a response to an existing entry. Evidence requires source + stance. Challenges require target_assertion + basis + argument (min 20 chars). Updates require update_type. Resolutions require outcome + source + resolution_type.
acta_queryBrowse the Acta public record. List topics (optionally filtered), get entries for a topic (with type/state filters), or look up a single entry with its responses.
acta_discoverFind actionable work across the Acta record. Surfaces contested records needing evidence, claims with no evidence, predictions approaching resolution, and recently active topics. This is the "where am I needed?" tool.
acta_verifyVerify the hash chain integrity for a specific topic. Returns chain length, chain head hash, and any integrity issues. Note: this is operator-served verification. For independent verification, use acta_export and run verify.js locally.
acta_exportExport the full hash chain for a topic. Returns all entries with hashes for independent verification using tools/verify.js. Use this when you need to audit the record independently.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
ACTA_DEVICE_IDAuto-generated Device identity for budget/rate limitingACTA_INSTANCE_URLACTA_URLTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
6/6 tools missing one or more hints — acta_contribute (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); acta_respond (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); acta_query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
