Concept

MCP Servers are external services that expose tools and capabilities through the Model Context Protocol. By connecting MCP servers to Infisical, you can centrally manage access to tools like Notion, GitHub, Slack, and more. When you add an MCP server to Infisical, the platform discovers all available tools from that server and allows you to make them accessible through MCP Endpoints.

​
Supported MCP Servers

Infisical supports connecting to any remote MCP server that implements the Model Context Protocol over HTTP with OAuth authentication. Popular MCP servers include:
  • Notion - Search, create, and manage Notion pages and databases
  • GitHub - Manage repositories, issues, pull requests, and more
  • Slack - Send messages, manage channels, and interact with workspaces
  • Google Drive - Access and manage files and documents
  • Linear - Manage issues and projects
Infisical connects to MCP servers over HTTP using the standard remote MCP protocol.

​
Authentication

MCP servers typically require authentication to access their tools. Infisical supports OAuth authentication, which handles the authorization flow automatically. Some MCP servers support Dynamic Client Registration, which means Infisical can automatically register as an OAuth client. For servers that don’t support this (like GitHub), you’ll need to manually create an OAuth application and provide the client credentials.

​
Credential Modes

When adding an MCP server, you choose how credentials are managed:

Shared Credentials

You (the administrator) authorize the MCP server once, and all users who access tools through this server use your credentials.Best for: Shared service accounts, servers without per-user permissions, simplified management.

Personal Credentials

Each user must authenticate with the MCP server individually before using its tools. Their credentials are stored securely by Infisical.Best for: Per-user audit trails, user-specific permissions, compliance requirements.

Guide to Adding an MCP Server

In the following steps, we explore how to add an MCP server to your Agentic Manager project.
1

Navigate to MCP Servers

Head to your Agentic Manager project and select MCP Servers from the sidebar, then click Add MCP Server.mcp servers list
2

Configure server details

Enter the following details for your MCP server:
  • Name: A friendly name to identify this server (e.g., “Notion”, “GitHub”)
  • URL: The MCP server endpoint URL (e.g., https://mcp.notion.com/mcp)
  • Credential Mode: Choose between Shared Credentials or Personal Credentials mcp server add
3

Configure authentication

For OAuth authentication, you may need to provide credentials depending on the server:For servers with Dynamic Client Registration (e.g., Notion):
  • Simply click Authorize to complete the OAuth flow
For servers without Dynamic Client Registration (e.g., GitHub):
  • Create an OAuth application in the service’s developer settings
  • Enter the Client ID and Client Secret
  • Click Authorize to complete the OAuth flow mcp server auth

Review available tools

After authorization, Infisical discovers and displays all tools available from the MCP server.You can view each tool’s name and description. These tools can now be enabled in MCP Endpoints.mcp server tools

FAQ

Each MCP server provider publishes their endpoint URL. Common examples:
  • Notion: https://mcp.notion.com/mcp
  • GitHub: https://api.githubcopilot.com/mcp/
Check the service’s MCP documentation for the correct URL.
  1. Go to GitHub Settings → Developer settings → OAuth Apps
  2. Click “New OAuth App”
  3. Set the Authorization callback URL to your Infisical instance
  4. Copy the Client ID and generate a Client Secret
  5. Use these credentials when adding the GitHub MCP server
Yes, you can update the credential mode by editing the MCP server configuration. Note that changing from shared to personal credentials will require users to re-authenticate.
If an MCP server becomes unavailable, tool invocations through endpoints connected to that server will fail. The Activity Logs will capture these failures for troubleshooting.
