Summary

Connects Claude to a curated knowledge base of researched answers from official documentation, specs, and RFCs across 40+ developer domains. Exposes four tools: ask_question for expert answers with sources, preflight_check to verify what knowledge exists before starting work, search_questions to browse by topic, and get_stats for coverage metrics. Free tier gives you 300 queries per month with no API key required. Reach for this when you want answers vetted against canonical sources rather than general web search results, especially for database engines like PostgreSQL and MySQL, frameworks like Next.js and Django, or infrastructure tools like Docker and Kubernetes.

AgentsKB MCP Server

Give Your AI Expert-Level Knowledge

Researched answers to any problem. Your AI, upgraded.

About this repository: AgentsKB is a hosted MCP server — there is no server to build or run locally, and this repository contains no source code. It exists to document the endpoint and to collect bug reports. Point your MCP client at the URL below and you are done.

Installation

The server is hosted at https://mcp.agentskb.com/mcp-kb and speaks MCP over streamable HTTP. No API key and no signup are required.

Claude Code

claude mcp add --transport http agentskb https://mcp.agentskb.com/mcp-kb

Add --scope user to make it available in every project instead of just the current one. Verify the connection with:

claude mcp list

Claude Desktop, Cursor, Cline, and other MCP clients

Add this to your client's MCP configuration file:

{
  "mcpServers": {
    "agentskb": {
      "type": "http",
      "url": "https://mcp.agentskb.com/mcp-kb"
    }
  }
}

Config file locations:

ClientFile
Claude Code (per-project).mcp.json in the project root
Claude Code (global)~/.claude.json
Claude Desktopclaude_desktop_config.json
Cursor (global)~/.cursor/mcp.json
Cursor (per-project).cursor/mcp.json in the project root

Cursor does not use the type field — for Cursor, list url on its own.

Some older clients do not support remote HTTP servers and only launch local processes. If yours is one of them, bridge to the endpoint with mcp-remote:

{
  "mcpServers": {
    "agentskb": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.agentskb.com/mcp-kb"]
    }
  }
}

REST API (no MCP client)

The knowledge base is also reachable over plain HTTP, with no key:

curl -X POST https://agentskb-api.agentskb.com/api/free/ask \
  -H "Content-Type: application/json" \
  -d '{"question":"What is a PostgreSQL index scan?"}'

What makes us different

Your AI searches. We research. That's the difference.

  • Dedicated research per question - not a side task while debugging
  • Official sources only - docs, specs, RFCs
  • Would rather not answer than guess wrong

Tools

ToolArgumentsDescription
ask_questionquestion*, domain, limitExpert-quality answers with sources
preflight_checktask*, depthSee what verified knowledge exists for your task
search_questionsquery*, domain, limitBrowse Q&As by topic
get_stats—Coverage metrics
consult_taxonomypath, depthNavigate the knowledge taxonomy
check_prerequisitesdomain*Foundational topics to understand first
get_lockfile_status—Check whether strict/pinned-answer mode is active

* required. question and query expect a full natural-language question — bare keywords such as mysql are rejected.

The server also exposes two resources: agentskb://context/current (detected project stack) and agentskb://context/prompt (a system-prompt fragment for that stack).

Coverage

55,000+ Q&As across 287 domains. The deepest coverage today is:

  • Databases and ORMs: PostgreSQL, Prisma, Drizzle
  • Frameworks: Next.js, NextAuth, Vue
  • Infrastructure and tooling: Docker, Bash, nginx, Git

Call get_stats for live counts, or consult_taxonomy to browse the full domain list.

Coverage is uneven and still growing. If you ask about a topic that is not yet covered, the server queues it for research and replies Topic '<name>' research queued instead of returning an answer — ask again later.

  • @agentskb/cli on npm: https://www.npmjs.com/package/@agentskb/cli — a separate tool for pinning and verifying answers in a repo (init, check, lock, request, update, verify). It does not implement an MCP server and is not needed to use the endpoint above.
