Replit Agent connects to external tools and data sources through the Model Context Protocol (MCP), an open standard for AI integrations. Each server below installs with a single click — Agent then automatically loads its tools and uses them when appropriate. For the concept, see Model Context Protocol. For the hands-on guide, see Connect via MCP. To connect a server that isn’t listed here, see Add a custom MCP server.
Select Add to Replit to install any server. You’ll be prompted to authorize the connection in the Project Editor.

Security protections

All MCP traffic passes through Replit’s security scanner. The scanner evaluates tool definitions and planned executions, blocking suspicious or unsafe tools before they run. If a tool is rejected, Agent will inform you about it.

Authentication options

  • OAuth dynamic client registration — if the server supports OAuth DCR, Replit automatically detects and registers the client for you. Most pre-listed servers use this flow.
  • Custom headers — define one or more header name/value pairs (for example, X-API-Key). Replit includes these headers in every MCP request so your server can verify the caller. Use this when adding a custom server that authenticates via static tokens.
Install links add your MCP server to Replit with a single click. Generate one with the form on Connect via MCP, or build it yourself: base64-encode a JSON payload and append it to https://replit.com/integrations?mcp=.
  • displayName — the name shown during installation
  • baseUrl — your MCP server’s HTTPS endpoint
  • headers — optional authentication headers
