Connect Claude or Codex to Agent Bayes

Connect your assistant to Agent Bayes and it can work with your library directly: run semantic search over your papers, put a question to the Agent Bayes research agent and get back a cited answer, or build a mindmap out of what it finds.

What your assistant can do

Manage projects
Manage knowledge bases
Index papers
Search your library
Create and edit mindmaps
Work with the mindmap agent
Synthesize cited claims and prose

Example

From a topic to a cited draft

Give Claude the whole job in one prompt. It finds papers on your topic, uploads them into a new knowledge base, and waits for indexing. Then it asks the Agent Bayes agent what those papers say, and the agent answers with citations. What comes back is a draft where every claim points at a passage and a page.

Your prompt

Create an Agent Bayes project on <topic>. Find the 15 most
relevant open-access papers, upload and index them into a new
knowledge base, then use the Agent Bayes agent in Ask mode to
learn the field, build the main arguments, and draft a full
article with citations.

Installation

Connected in three steps

1. Create a key
In the app, open Settings → API Keys and click Create API key. The key appears once. Copy it now. If you use more than one device, make a key for each, so you can revoke one without breaking the others.

2. Tell your assistant about it

Claude Code

claude mcp add --transport http agent-bayes \
  https://api.agentbayes.com/mcp/ \
  --header "X-API-Key: sk-your-key"

Codex, in ~/.codex/config.toml

[mcp_servers.agent-bayes]
url = "https://api.agentbayes.com/mcp/"
http_headers = { "X-API-Key" = "sk-your-key" }

Cursor, or any client that takes a JSON config

{
  "mcpServers": {
    "agent-bayes": {
      "url": "https://api.agentbayes.com/mcp/",
      "headers": { "X-API-Key": "sk-your-key" }
    }
  }
}

The same key also works as Authorization: Bearer sk-your-key if your client prefers standard bearer headers.

3. Ask something
Try: "Look at my Agent Bayes projects and tell me what my papers say about X, with citations." Your assistant reads the operating manual first, then gets to work.

Good to know

Your key is your account. If it leaks, revoke it in Settings and the connection dies at once.
Reading is free, spending is announced. Indexing and agent runs cost credits, and say so before your assistant uses them.
Same plan, same limits. Your assistant sees what your account can see, and nothing more.
