Model Context Protocol (MCP) is an open standard for connecting AI agents to external tools and data sources. Lyzr supports MCP, letting you connect any MCP server to your agents.

​
Connection: Phase 1: Register the MCP Server

  1. Tools → Add MCP Server
  2. Enter the MCP Server URL
  3. Select authentication method (API Key or OAuth)
  4. Click Connect
The server is now registered and available across your organization. Anyone in your workspace can add it to their agents.

​
Authentication options

API Key Enter the API key for the MCP server. Lyzr stores it encrypted and passes it in the Authorization header automatically. OAuth Lyzr initiates the OAuth flow. After authorization, tokens are stored and refreshed automatically. Registering an MCP server doesn’t automatically give all agents access, you explicitly select it per agent.
  1. Open the agent → Tools → enable → select the MCP server
  2. Review the actions exposed by the server
  3. Select only the actions this agent should use
  4. Save
Principle of least privilege: Only expose the specific MCP actions your agent needs. An agent that reads project status doesn’t need write access to create or delete resources.

​
Testing

After linking, use the test panel in the agent builder to verify the MCP tools are callable. The trace will show MCP tool calls under Tool Calls in the trace detail.

Lyzr as an MCP server

Lyzr Cognis (memory) is available as an MCP server, letting external tools like Cursor, Claude Desktop, Zed, and Opencode use Cognis for memory:
