MCP tool discovery for AI agents — find, compare, verify tools across 35+ registries.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.
How we verified
Verified is a snapshot. Live keeps it current, and builds your track record.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
When Vitest UI server is listening, arbitrary file can be read and executed
Vitest allows Remote Code Execution when accessing a malicious website while Vitest API server is listening
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
TOOLCAIRN_EVENTS_PATHTOOLCAIRN_TRACKING_ENABLEDtrue Set false to disable usage event logging (see [Privacy](#privacy--telemetry)).TOOLPILOT_API_URLSelf-hosted backend. Set =https://your-host.TOOLPILOT_MODETool 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
18/18 tools missing one or more hints — toolcairn_auth (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); classify_prompt (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); toolcairn_init (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 3/18 tools referenced in tests (17%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (test-e2e.mjs:38)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
7 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
