Funnel

You add Funnel MCP to Claude Desktop by editing <code>claude_desktop_config.json</code> manually because your organization does not offer Add custom connector. OAuth discovery succeeds, but connection fails during dynamic client registration and no Funnel sign-in window opens.

The MCP server starts and OAuth discovery succeeds, but setup fails at dynamic client registration. <code>mcp-remote</code> reports a <code>ServerError</code> against <code>login.funnel.io/oidc/register</code> and no sign-in window opens.

A typical failing configuration looks like this:

"funnel": {
  "command": "npx",
  "args": ["-y", "mcp-remote@latest", "https://mcp.ai.funnel.io/mcp"]
}

When you configure Funnel MCP manually in Claude Desktop with <code>mcp-remote</code> in <code>claude_desktop_config.json</code>

When your Claude organization does not show Add custom connector and you cannot use the in-app connector flow

After OAuth discovery succeeds but registration against <code>login.funnel.io/oidc/register</code> fails before sign-in

- When you configure Funnel MCP manually in Claude Desktop with <code>mcp-remote</code> in <code>claude_desktop_config.json</code>
- When your Claude organization does not show Add custom connector and you cannot use the in-app connector flow
- After OAuth discovery succeeds but registration against <code>login.funnel.io/oidc/register</code> fails before sign-in

<code>mcp-remote</code> attempted dynamic OAuth client registration without a static OAuth Client ID from Funnel. For manual Claude Desktop setups, registration at the OIDC register endpoint can fail and block the sign-in flow until you pass Funnel's static OAuth client details to <code>mcp-remote</code>.

Confirm your Remote MCP server URL matches your Funnel region:

- Global (default): <code>https://mcp.ai.funnel.io/mcp</code>
- EU: <code>https://mcp.eu.ai.funnel.io/mcp</code>

Copy Server URL from Connect Funnel MCP in Funnel AI full view (Data &gt; Analyze &gt; Funnel AI).

Copy your OAuth Client ID from the same Connect Funnel MCP modal. Expand Advanced if your client requires static OAuth registration.

Replace your <code>claude_desktop_config.json</code> entry with static OAuth client info. Substitute the placeholders below:

- <code>{mcp_server_url}</code> — your Funnel MCP server URL from step 1
- <code>{local_callback_port}</code> — a local port for the OAuth callback (for example <code>17207</code>)
- <code>{oauth_client_id}</code> — your OAuth Client ID from step 2

<code>json "funnel": { "command": "npx", "args": [ "mcp-remote", "{mcp_server_url}", "{local_callback_port}", "--static-oauth-client-info", "{\"client_id\":\"{oauth_client_id}\"}" ] }</code>

Restart Claude Desktop and complete the Funnel sign-in flow when the browser window opens.

If registration still fails, contact <a href="https://help.funnel.io/en/articles/6280750">Funnel support</a>. Include:

- Your MCP server URL
- That you are using manual <code>mcp-remote</code> configuration in Claude Desktop
- The full error text from <code>mcp-remote</code> or Claude Desktop logs
- When the issue started

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
