"Known" matching MCP servers:

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

MCP server to query and manage CISA Known Exploited Vulnerabilities catalog with EPSS overlay, enabling vulnerability checks and remediation deadline tracking.

Knownbase gives AI agents durable, structured project memory that persists across sessions, tools, and workflows. Through MCP, agents can store and retrieve Markdown-based knowledge such as architecture decisions, debugging discoveries, implementation details, handoffs, project facts, and ongoing work. Notes can be organized by project, tags, status, and structured metadata, then searched efficie

Generates signed .well-known MCP server cards (SEP-1649/1960/2127) to enable MCP server discovery and compliance.

Provides verified fixes for real developer errors to AI agents via MCP, with free sample fixes and paid per-lookup transactions on Base mainnet. Enables searching fixes, browsing the catalog, retrieving offers and fixes, and submitting new fixes.

Enables searching and reading AVEVA Customer Support Portal knowledge base articles, including tech notes, known issues, and error-message diagnostics, to ground AI answers in support content not found in public documentation.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

Helps AI agents avoid repeating known failures by providing deterministic lookup of dead ends for coding errors and country-specific real-world rules.

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.

Safe-upgrade advisor for OpenClaw. Detects current version, checks the deployment against a hand-curated catalog of version-specific known regressions, captures pre-upgrade snapshots, diffs them against post-upgrade state, and emits step-by-step upgrade + rollback guides.

Enables AI agents to query a public signed ledger of known failures and fixes before retrying, then ingest, confirm, fail, and share dense claims so subsequent agents avoid paying the same cost.

The IDE for agents — read by symbol, edit against a revision, validate with your own build, revert. It is a local stdio MCP server for coding agents. It reads code by symbol with tree-sitter and real language servers (Go, Java, Scala, TypeScript, Python, Rust, Ruby), edits against a known revision and returns compiler diagnostics with each edit, runs the repository's own build, test etc.

Enables AI agents to search, correlate, and monitor real-time vulnerability intelligence from NVD, CISA KEV, EPSS, and MITRE ATT&CK, including CVE details, critical CVE tracking, known exploited vulnerabilities, and exploitation probability scores.

Persistent AI agents memory for Claude, Codex, Cursor... that is always current.

MCP server that helps coding LLMs avoid re-solving common problems by serving verified minimal code samples and compatibility evidence, with tools to search, retrieve, and explain known solutions across languages and environments.

An MCP server that verifies npm and PyPI packages before installation, checking for existence, known vulnerabilities, OpenSSF scorecard, and typosquatting, returning an ALLOW/WARN/BLOCK verdict.
