"Known" matching MCP servers:

Enables searching and analyzing Ceph issues from multiple trackers, providing tools to find known issues, workarounds, and fixes.

Checks whether release notes cover the feature changes, fixes, and known issues provided by the user.

Provides Canada-aware vehicle intelligence for AI agents, including VIN decoding with factory warranty terms, merged US/Canada recalls, known-issue reports, and itemized purchase costs, with pay-per-call settlement via USDC on Base using x402.

Give your AI coding agent the Roblox DevForum and official creator docs — check if a bug is already known, read the accepted answer, and verify APIs before writing Luau.

Query CVEs, yanked releases, known exploits, and upgrade paths for any PostgreSQL version directly from your AI assistant.

Enables checking IP addresses against the GreyNoise API to determine if they are internet background noise, known benign services, or potentially targeted threats.

Security scanner for vibe coders that checks npm packages for known vulnerabilities before installation, integrating with AI coding tools like Claude Code and Cursor.

Search and contribute to FixGraph — 25,000+ community-verified engineering fixes. Tools: fixgraph_search, fixgraph_get_fixes, fixgraph_submit_fix.

MCP server for UK Freedom of Information research. Connects AI assistants to WhatDoTheyKnow — the UK's largest FOI request platform to search requests, read responses, look up public authorities, and draft new requests.

Enables AI-assisted remote server diagnostics by auto-executing known read-only commands and routing high-risk changes to a real human for approval through DingTalk interactive cards. It uses structured argv instead of shell strings, default-deny policy, and HMAC-signed agent execution with hash-chained auditing so the model never holds SSH keys or approval power.

The most capable Monarch Money MCP server, merging the best features from all known implementations into one clean TypeScript project. It provides 47 tools for comprehensive personal finance management including transactions, budgets, rules, merchant management, and intelligence analysis.

Enables medical evidence retrieval and analysis via AI-powered search and summarization tools.

Enables checking npm packages for known security vulnerabilities using the OSV API before installation. Supports both single package checks and bulk vulnerability scanning for multiple packages at once.

A server that helps discover and analyze websites implementing the llms.txt standard, allowing users to check if websites have llms.txt files and list known compliant websites.

MCP server that wraps the official JPO patent information API to enable retrieval of patent, trademark, and design records for known case numbers.

Provides a runtime interface that lets AI coding agents query governed Git-backed artifacts such as skills, context, and policies while reading and writing dynamic project memory—feature and decision records, observations, known issues—persisted in PostgreSQL. Supports project registration, scoped context and memory search, skill resolution, and role-gated memory promotion through API keys.

Enables agents to discover and call thousands of live agent tools with known prices, claim escrowed tasks, and settle payments via x402.

Enables AI clients to search Shopify stores and contacts by market, traffic, revenue, apps, pixels, themes, ads, or contact availability, enrich known domains, preview matching contacts, and reveal selected contact details after approval via OAuth.

Enables auditing an AI agent's guardrails by providing adversarial test prompts and scoring responses against known refusal/guardrail patterns.

Provides access to CISA's Known Exploited Vulnerabilities catalog via the Model Context Protocol, enabling querying, searching, and analyzing vulnerability data.
