"HERE" matching MCP servers:

A comprehensive MCP server for checking package versions and rating package quality across Python (PyPI), JavaScript/TypeScript (npm), Dart (pub.dev), and Rust (crates.io) ecosystems.

Enables a primary Codex agent to queue independent, read-only research jobs that execute in parallel using any OpenAI Responses-compatible inference provider while the agent continues its own work.

Verified, version-pinned records of new dependency bugs. When your coding agent hits an error it cannot fix in one try, it looks the error up here before searching the web: on 56 fresh bugs it said correctly whether the bug was known or fixed 91% of the time with Cairn, 68% without. Read-only by default. Benchmark and data (CC BY 4.0): https://cairncommons.dev/benchmark

AgentRoots is an MCP server for agent continuity that preserves goals, findings, and evidence across sessions. It enables agents to propose, review, and reuse compact, evidence-backed state instead of replaying transcripts.
