Replit Agent can connect to hundreds of external tools and data sources through the Model Context Protocol (MCP) — an open standard for AI tool integrations. Sign in to a pre-listed server or add any custom MCP server you trust.

​
Connect a pre-listed MCP server

Replit ships with a curated list of MCP servers for popular services like Stripe, Linear, Notion, Sentry, and more. Connecting is a single sign-in click.

1

Open the Integrations pane

Go to replit.com/integrations and scroll to MCP Servers for Replit Agent.
2

Pick a server

Find the service you want to connect — Stripe, Linear, Notion, Sentry, Atlassian, Miro, PostHog, Amplitude, Mixpanel, Granola, Razorpay, and others.
3

Sign in

Click Sign in next to the server. You’ll be guided through the OAuth flow with that service. Once connected, the server’s connection status updates and Agent can use its tools.
For the full catalog, see the MCP Servers reference.

​
Add a custom MCP server

If the server you want isn’t in the pre-listed catalog, add it by URL.

1

Open the add-server dialog

On the MCP Servers settings pane, click + Add MCP server.
2

Set a display name

Provide a recognizable name — Agent uses it to reference the server in chat logs.
3

Enter the server URL

Paste the MCP server’s HTTPS endpoint. Open Advanced settings to add custom headers (e.g. X-API-Key) if the server needs authentication.
4

Test & save

Click Test & save. Replit attempts to connect and walks you through any OAuth flow the server requires. Once saved, the connection appears under MCP Servers with its status.
Only connect to MCP servers you trust. A connected server can provide tools and data to Agent — review the source before adding any unfamiliar endpoint.

​
Use MCP tools in Agent

After a server is connected, Agent automatically fetches its tool list and makes the capabilities available across all your projects. To use a server, just mention it in chat:
Use the Notion MCP server to find the most recent meeting notes.

Agent picks the right tools from the server based on your request. If a tool requires confirmation, you’ll see a prompt before it runs. Install links let anyone add your MCP server to Replit with a single click — useful for documentation, READMEs, or anywhere you want to promote your integration. Use the form below to generate an install link and a clickable badge for your server: For the link format and badge customization options, see the Install Links reference.
