What are MCP Clients?

MCP clients let your organization connect to external MCP servers, making third-party tools available to your Logic documents and agents during execution. While Logic’s MCP server exposes your documents as tools for external AI platforms, MCP clients work in the opposite direction — they bring external tools into Logic.
MCP Server vs. MCP Client: An MCP server lets external AI platforms (like Claude or ChatGPT) call your Logic documents. An MCP client lets your Logic documents call tools hosted on external MCP servers.
MCP client integrations are not currently available for HIPAA-compliant organizations.

​
Creating an MCP Client

You can create MCP clients from the MCP Clients section of your organization settings in the Logic dashboard. To add a new client:
  1. Navigate to Organization Settings > MCP Clients.
  2. Click Add MCP Client.
  3. Fill in the required fields:
    • Name — A unique name for this client.
    • URL — The URL of the external MCP server.
    • Description — A brief description of what this client provides.
    • (Optional) Auth Token - An authentication Bearer token if required by the server (see below)
  4. Click Save.

​
Authentication

MCP clients support three authentication types for connecting to external servers. You can configure the authentication method when creating or editing a client in the dashboard.

​
None

No authentication required. Use this for MCP servers that are publicly accessible or rely on network-level security. Leave the Auth Token section empty.

​
Bearer Token

Use this for MCP servers that require a secret token. Enter the token value in the dashboard. Logic will send it as a Bearer token in the Authorization header on each request.

​
OAuth

Logic will automatically detect MCP servers that use OAuth 2.0 authentication. Click the Authorize button to complete the OAuth workflow. Token information will be stored automatically upon success.
Logic will automatically attempt to refresh OAuth tokens before they expire. If automatic refresh fails, you can manually refresh tokens from the MCP Clients page in your organization settings.

​
Using MCP Clients with Documents

Once you’ve created an MCP client, you need to connect it to the documents that should have access to its tools:
  1. Link the MCP client to your document — Open the document in the Logic dashboard and add the MCP client from the document’s Tools panel.
  2. Update your document contents — In your document, specify where and how the MCP client’s tools should be used. The agent will have access to the linked tools during execution.

​
Managing MCP Clients

You can view, edit, and delete MCP clients from the MCP Clients section in your organization settings. From there you can update connection details, change authentication credentials, or remove clients that are no longer needed.
