Modem MCP Server

Modem MCP Server

Connect Modem to any MCP-compatible client. Modem builds a custom context graph of your customers and product, grouping disparate data from chat, issue trackers, and support inboxes into topics, people, and companies. From your assistant you can search that graph, run the Modem Agent, and update your workspace directly.

https://mcp.modem.dev/mcp

This repo holds the public manifests, install docs, and listing assets for the Modem MCP server. The server itself is a hosted service; there is nothing to run from this repo.

What you can do

Kind Tools Scope
Run the Modem Agent modem_agent_invoke, modem_agent_get_run, modem_agent_send_message, modem_agent_cancel_run agent:invoke
Search your data search_modem — natural-language search over topics, messages, people, companies data:read
Update your workspace update_topic, bulk_update_topics, merge_topics, create_companies, update_companies, merge_companies, add_people_to_company, update_people, merge_people agent:invoke

Write tools act as you, under your existing role in the organization you authorize — never more access than your Modem account already has. All writes are annotated destructive, so most clients confirm each call.

Install

In every client, the server URL is https://mcp.modem.dev/mcp. The first connection opens a browser window for OAuth authorization.

Claude Code

claude mcp add --transport http modem https://mcp.modem.dev/mcp

Then run /mcp inside Claude Code and complete the browser authorization flow.

Cursor

Settings → Cursor Settings → Tools & MCP → add a new MCP server, or add to mcp.json:

{
    "mcpServers": {
        "modem": {
            "url": "https://mcp.modem.dev/mcp"
        }
    }
}

If Cursor asks for a transport type, choose Streamable HTTP.

VS Code / GitHub Copilot

In your user profile mcp.json or workspace .vscode/mcp.json:

{
    "servers": {
        "modem": {
            "type": "http",
            "url": "https://mcp.modem.dev/mcp"
        }
    }
}

Or use MCP: Add Server from the command palette.

Codex

codex mcp add modem --url https://mcp.modem.dev/mcp
codex mcp login modem

Or in ~/.codex/config.toml:

[mcp_servers.modem]
url = "https://mcp.modem.dev/mcp"

If you edit config.toml directly, you still need codex mcp login modem to complete OAuth.

Gemini CLI

This repo is a Gemini CLI extension (see gemini-extension.json):

gemini extensions install https://github.com/modem-dev/mcp

Then authorize when prompted on first use (or run /mcp auth modem inside Gemini CLI).

opencode

In opencode.json:

{
    "$schema": "https://opencode.ai/config.json",
    "mcp": {
        "modem": {
            "type": "remote",
            "url": "https://mcp.modem.dev/mcp"
        }
    }
}

Then opencode mcp auth modem (or authorize when prompted on first use).

Any other MCP client

Field Value
Name modem
URL https://mcp.modem.dev/mcp
Transport Streamable HTTP (or "HTTP")
Authentication OAuth

Example prompts

  • "What are customers saying about billing in the last month?"
  • "Summarize the three highest-priority open topics and who's affected."
  • "Mark the topic about SSO login failures as high priority in Modem."
  • "Find the duplicate Acme companies in Modem and merge them into the one with the acme.com domain."

Security and access

  • OAuth tokens are scoped to the account and organization selected on the consent screen; the server resolves the organization from token claims, never from the URL.
  • Two permissions, granted separately: data:read (natural-language search only) and agent:invoke (agent runs + workspace writes).
  • Tool calls are rate limited per organization, per tool (20/min).
  • Privacy policy: https://modem.dev/privacy-policy · Terms: https://modem.dev/terms-of-service · Trust center: https://trust.modem.dev
