AI agentsCustom connector · MCP
Add Lumenbase as a custom connector in Claude, then use CRM tools in chat. This uses the production remote MCP endpoint with workspace-scoped access.
- Good for
- Claude.ai, Claude Desktop, Cowork (directory connector)
- Sign in
- OAuth (Connectors); stdio uses personal token
What this is
Connect Lumenbase inside Claude as a custom connector. You paste one URL in Claude, sign in on Lumenbase when prompted, and Claude can use your CRM tools in chat. Same data as the app and OpenClaw, scoped to your workspace.
This guide is for Claude on the web and Claude Desktop when they support remote MCP + OAuth. For a local MCP file on your computer, see the advanced section at the bottom.
How to use Lumenbase in Claude
Add Lumenbase as a custom connector in Claude, sign in once on Lumenbase, then use CRM tools from chat.
Open Customize
In Claude, open Customize. You will see Skills, Connectors, and plugins in the sidebar.
- Open Customize from the Claude sidebar or menu
- You should see Skills, Connectors, and Connect your apps
Click Connectors
Open Connectors from Customize. Before adding Lumenbase, your custom connector list should be empty.
- Open Connectors and verify the list is empty before adding Lumenbase
- Then click + to add your custom connector
Click +, then Add custom connector
In Connectors, click + and choose “… Add custom connector” from the menu.
- Click + in Connectors, then choose “… Add custom connector”
- The Add custom connector dialog opens next
Give the name and put the Remote MCP server URL
In the Add custom connector dialog, set the name to Lumenbase and paste the Remote MCP server URL, then click Add.
MCP server URL (paste in Claude)
https://lumenbase.io/api/mcp
Leave OAuth Client ID and Client secret empty in Claude — registration is automatic. Only fill them if your admin gave you Anthropic-held credentials (claude-connector plus a secret).
- Name: Lumenbase
- Remote MCP server URL: https://lumenbase.io/api/mcp, then click Add
It will look like this when connected
On the new Lumenbase connector row, click Connect or Authorize and allow access on Lumenbase. After approval, Claude shows Lumenbase as connected with URL and tool permissions.
- After approval, the connector appears under Web as connected
- You should see URL + tool permissions and a Disconnect button
Consent URL (only from Claude): lumenbase.io/oauth/claudeStart a chat and make a CRM request
Return to Claude, start a chat, and ask for a CRM action within Lumenbase capabilities, like creating or listing records.
- Start a chat and make a CRM request in plain language
- Approve the prompt when Claude asks to use Lumenbase tools
How auth works
Where auth happens: after you save the connector in Claude, use Connect or Authorize on that connector. Claude sends you to lumenbase.io/oauth/claude to sign in and approve. Lumenbase returns an OAuth token to Claude. You never paste a CRM password into Claude.
Revoke anytime: Settings → My Integrations → OpenClaw, then delete the row labeled Claude connector.
What Claude can do
After you connect, Claude can call 22 CRM tools in your workspace. They respect the same data-access rules as Lumo and OpenClaw.
Look up
Search and summarize your workspace without changing data.
Create
Add new records and notes when you ask Claude to.
Update
Change fields on existing records.
Remove
Only when you explicitly ask. Claude flags these as destructive.
Outreach
Send email or LinkedIn messages when you ask (remote queue requires extension session).
Advanced: local MCP (stdio)
For Claude Desktop or Cursor with a local MCP process, generate a personal token under Settings → My Integrations → OpenClaw and follow the Claude Desktop (stdio) card there. That path does not use Connectors or OAuth.
Prefer the remote connector above when Claude supports it. No API token stored in a file on disk.
Events
CRM changes from connector tools can emit outbound events (Zapier, webhooks) when enabled for your workspace. Configure under Settings → Integrations. See Zapier setup.
