The standard

One protocol, every AI client.

MCP lets AI clients call tools on your server directly. No plugins, no scraping, no glue code.

01

Works everywhere

Plug into Claude Desktop, Cursor, Cline, ChatGPT desktop, or any MCP-compliant AI client.

02

One API key

Use the mk_* key from Settings → API & Agents. One quota covers REST and MCP.

03

Read-only

No tool can edit, claim, or delete. Safe to give to autonomous agents.

Tool reference

What the model can do

Six read-only tools cover discovery, drill-down, and graph traversal. Each returns paginated JSON your model can parse natively.

list_people

Search and filter the people graph. Free-text, location, employer, title, founder / investor / verified flags.

get_person

Fetch a single person by slug or ID. Optionally include their companies, investments, and social links.

list_companies

Search and filter companies. Industry, location, status, and a has_funding flag for funded-only views.

get_company

Fetch a single company. Includes team, funding rounds, and (optionally) investments and social links.

list_investors

Search and filter VC firms. Filter by founding year window, status, or minimum recorded investments.

get_investor

Fetch a single VC firm. Returns people at the firm, portfolio investments, and aggregate statistics.

Pagination is uniform: limit (1–100, default 25) and offset. Slugs accept either the URL slug or a numeric ID.

How it works

Three steps. You're done in under two minutes.

From zero to a working tool call inside Claude Desktop. No SDK install, no build step, no webhook plumbing.

01

Sign in and open Settings → API & Agents

From your Mentibus dashboard, head to Settings → API & Agents. You'll see your existing keys and a button to mint a new one.

02

Create a key with the read permission

Name it after the client you'll connect (e.g. claude-desktop). The mk_… token is shown once, so copy it immediately. Mentibus only stores its hash.

03

Drop the URL and key into your MCP client

Each client has a tiny JSON config block. Pick yours below, paste in the URL and your key, restart the client, and the Mentibus tools appear.

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "mentibus": {
      "url": "https://mentibus.xyz/mcp",
      "headers": {
        "Authorization": "Bearer mk_your_key_here"
      }
    }
  }
}
Replace mk_your_key_here with your key, restart the client.

Cursor

Settings → MCP → Add new MCP server

{
  "mentibus": {
    "url": "https://mentibus.xyz/mcp",
    "headers": {
      "Authorization": "Bearer mk_your_key_here"
    }
  }
}
Replace mk_your_key_here with your key, restart the client.

Cline (VS Code)

cline_mcp_settings.json

{
  "mcpServers": {
    "mentibus": {
      "transport": "http",
      "url": "https://mentibus.xyz/mcp",
      "headers": {
        "Authorization": "Bearer mk_your_key_here"
      }
    }
  }
}
Replace mk_your_key_here with your key, restart the client.

Anthropic Python SDK

messages.create(mcp_servers=[…])

import anthropic

client = anthropic.Anthropic()
client.messages.create(
    model="claude-opus-4-7",
    max_tokens=1024,
    mcp_servers=[
        {
            "type": "url",
            "url": "https://mentibus.xyz/mcp",
            "name": "mentibus",
            "authorization_token": "mk_your_key_here",
        }
    ],
    messages=[{"role": "user", "content": "Find recent VC firms in San Francisco."}],
)
Replace mk_your_key_here with your key, restart the client.

Need ChatGPT desktop, Cline-Server, or a custom OpenAI agent? The server speaks vanilla MCP. Point any compliant client at the URL.

What people build

From conversation to research, instantly

The MCP surface turns the Mentibus graph into a first-class citizen of your agent's reasoning loop. A few sketches.

Founder discovery in chat

Ask Claude: "Find me five seed-stage founders in NYC working on agent infra." The model fans out list_people calls, drills into get_person, and returns a vetted shortlist with bios.

Investor mapping

Cursor agent investigates "who funded Series A AI infra companies in 2024?" by chaining list_companies(has_funding=true) and get_company(include_funding=true). No scraping, no pasting CSVs.

Portfolio briefings

Drop your VC firm slug into get_investor and let the model summarize portfolio overlap, recent rounds, and team movements before a partner meeting.

Custom agent backends

Build a deal-flow agent on the Anthropic Messages API with mcp_servers=[…]. The model picks tools on its own. You ship the system prompt and the workflow.
