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:

Client	File
Claude Code (per-project)	.mcp.json in the project root
Claude Code (global)	~/.claude.json
Claude Desktop	claude_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

Tool	Arguments	Description
ask_question	question*, domain, limit	Expert-quality answers with sources
preflight_check	task*, depth	See what verified knowledge exists for your task
search_questions	query*, domain, limit	Browse Q&As by topic
get_stats	—	Coverage metrics
consult_taxonomy	path, depth	Navigate the knowledge taxonomy
check_prerequisites	domain*	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.
