Set up an MCP server

Register an MCP server with C1, link it to a C1 application, and configure authentication so C1 can govern access to its tools.

Activation required. AI access management must be enabled for your tenant before you can use it. To get started, contact the C1 support team for a walkthrough.

This page walks through registering an MCP server with C1, linking it to a C1 application, and configuring authentication. Once registered, C1 automatically discovers the tools the server exposes — see Govern tools and toolsets for what to do next.

Before you begin

• AIAM must be enabled for the tenant. See Enable AI access management.
• For OAuth-based auth, you’ll need a client ID and secret from the downstream service.
• For per-user OAuth, the downstream service must be reachable by C1’s hosted callback URL.

Register an MCP server

1. In C1, go to Integrations > MCP servers.

2. Click Add an MCP server.

3. Select the MCP server you want to govern (for example, Salesforce, Google Analytics, or GitHub).

4. Select which application the MCP server should be registered under:

   • Add to an existing managed or unmanaged app — select this if you already have a connector-backed C1 app for the same downstream service. The MCP server registers under that app and inherits its user assignments.
   • Create a new app — select this if you do not have a connector-backed app for the service. C1 creates a new app for the MCP server. You will need to add users to this app before they can request access to its tools.
5. Click Register. C1 connects to the server, validates it, and runs initial tool discovery.

After registration, the server appears in Integrations > MCP servers with its discovered tools listed under the Tools tab and in the connected app’s details page.

Configure authentication

C1 supports multiple auth methods for downstream MCP servers. Admins can select any supported method when configuring a server.

Method	Who the downstream sees	When to use
Bearer token	A single shared service account	Simple integrations where per-user attribution downstream isn’t required
Custom header	A single shared identity via a custom HTTP header (for example, an API key)	Services that authenticate via a non-standard header or API key
Basic auth	A single shared identity via username and password	Services that use HTTP Basic authentication
OAuth2 — client credentials	A single shared OAuth client	Machine-to-machine OAuth where per-user identity isn’t needed
OAuth2 — service mode	A single shared identity (admin authenticates once)	When the downstream requires an OAuth auth code flow but a single shared credential is acceptable
OAuth2 — per-user passthrough	Each end user, with their own credentials	When the downstream needs per-user identity (Google Workspace, GitHub, Salesforce, and so on)
OAuth2 — JWT bearer	A service identity via signed JWT	Services that support certificate-based or JWT-based auth (for example, Tableau or Google service accounts)

For per-user OAuth passthrough, C1 vaults each user’s downstream tokens and auto-refreshes them so end users don’t hit token expiry mid-session.

To configure auth:

1. From the registered server’s settings, click Edit authentication.

2. Select the auth method.

3. Enter the required credentials for the selected method:

   • Bearer token — paste the token. C1 vaults it.
   • Custom header — enter the header name and value.
   • Basic auth — enter username and password.
   • Client credentials — enter client ID, client secret, and token URL.
   • Service mode — enter client ID, client secret, authorization URL, token URL, and scopes. An admin completes the OAuth flow once; all users share that credential.
   • Per-user passthrough — enter client ID, client secret, authorization URL, token URL, and scopes. End users see a Connect prompt the first time their AI client calls a tool from this server.
   • JWT bearer — enter the issuer, private key, subject, audience, token URL, and scopes.
4. Click Save. C1 makes a test call to validate the credentials.

Configure server settings

Setting	Required?	What it does
Authentication	Required	See above
Data sensitivity	Optional	Metadata tag on the server (low / medium / high). Surfaces in the catalog and audit log; no enforcement
Tool prefix	Optional; required if multiple servers under one app	Prepended to tool names so AI clients can disambiguate (for example, gh_ vs gl_ for two Git providers). C1 generates a default prefix if you don’t set one.

What happens after registration

• C1 runs an initial tool discovery sweep against the server. Discovered tools appear under the Tools tab with state Pending Review by default.
• C1 re-runs discovery on a schedule. New tools appear as Pending Review; tools that disappear are flagged but not auto-deleted.
• No tool from this server is callable by any end user yet — see Govern tools and toolsets to approve, classify, and bundle them.
