ReplySparrow MCP
Use ReplySparrow from Claude, ChatGPT, Cursor, Codex, and other AI assistants.
The ReplySparrow MCP server connects your AI assistant to your ReplySparrow workspace. Ask in plain language, and the assistant finds leads, checks buying signals, builds lists and campaigns, and follows up on replies for you, using the same data and permissions as the app.
- "Who should I contact today, and why?"
- "Summarize the replies I got this week and draft answers to the interested ones."
- "Create a source agent for Heads of Sales at French SaaS companies, and a campaign for it."
How it works
- You add ReplySparrow to your assistant with the server URL below.
- The assistant asks you to sign in to ReplySparrow and approve the connection, choosing what it may do (read, write, run actions). No API key to copy.
- ReplySparrow gives the assistant its own access token for your workspace. It renews itself while you keep using the assistant.
- When you ask something, the assistant picks the right ReplySparrow tools, calls them, and answers with the results.
https://app.replysparrow.com/api/mcpIf you are using a custom MCP client, it must support MCP's OAuth sign-in (with dynamic client registration) and the Streamable HTTP transport. Requests without a valid access token are rejected with a 401 that points the client to ReplySparrow's sign-in.
The assistant acts as you, inside the workspace you approved, with the access levels you granted at sign-in. Tools that need a level you did not grant are refused. For scripts and your own code, use an API key and the API reference instead.
Connect your assistant
The same steps are on the MCP page of the app, under Settings → MCP.
Chat assistants
Add a custom connector named ReplySparrow with the server URL, click Connect, then sign in to ReplySparrow.
Turn on developer mode in Connectors, create a connector with the server URL, then sign in to ReplySparrow.
Add a remote MCP server named replysparrow with the server URL in Settings → MCP, then sign in to ReplySparrow.
Developer tools
Claude Code. Run this command, then sign in to ReplySparrow in the browser window that opens.
claude mcp add --transport http replysparrow https://app.replysparrow.com/api/mcpCodex. Run this command, then sign in to ReplySparrow in the browser window that opens.
codex mcp add replysparrow --url https://app.replysparrow.com/api/mcpOther assistants. Any assistant that supports remote MCP servers works: open its MCP or connector settings, add a server with the URL above, then sign in to ReplySparrow when asked.
ReplySparrow is not listed in the assistants' app directories yet; use the server URL to connect.
What the assistant can do
The tools cover the same data as the app and the API reference. The assistant chooses tools on its own; you never call them by name.

Tools that change or delete data are flagged as such, so assistants that support it ask you before running them. inbox_send_email sends a real email and cannot be undone.
Credits
Browsing your leads, signals, campaigns, and replies is free. Finding a lead's email or phone (lead_action with find_email or find_phone) uses workspace credits, at the same price as in the app, and the credit is refunded when nothing is found.
Teams
If you belong to several workspaces, ask the assistant to work in another one. It looks your workspaces up with workspaces_list, then switches with workspace_switch. Everything after that runs in that workspace for this connection until you switch back.
Disconnect
Remove the ReplySparrow connector in your assistant's settings. The assistant stops calling ReplySparrow, and its access token expires within the hour. Connecting again asks you to sign in and approve the connection again.
