Greptile MCP is a developer platform that indexes codebases, pull requests, and engineering knowledge. It helps teams find code quickly, review changes, and maintain reusable project context.

21 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Greptile account to Claude via Composio Connect, enabling it to search repo for security vulnerabilities across branches, summarize recent pull request comments and suggestions, create context bundle from project docs, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Greptile to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Greptile account

Back in Claude, ask it to connect to Greptile or give it any Greptile-related task.

For example, ask Claude to:

  • "Search repo for security vulnerabilities across branches"
  • "Summarize recent pull request comments and suggestions"
  • "Create context bundle from project docs"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Greptile account is ready to use.

What is the Greptile Claude Connector, and what's possible with it?

The Greptile MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Greptile account. It provides structured and secure access to your connected codebases, pull requests, code reviews, custom context, and engineering knowledge bases, so your agent can search technical knowledge, inspect code changes, trigger reviews, manage review rules, and analyze findings on your behalf.

  • Repository knowledge discovery: Have your agent discover connected repositories, browse their knowledge base documents, and search for specific symbols, endpoints, or engineering conventions.
  • Pull request investigation: Let the agent list and inspect pull requests or merge requests, including their metadata, statistics, comments, recent reviews, and cited summaries.
  • Code review management: Direct your agent to trigger a new code review for an existing pull request or merge request, then retrieve and track review runs.
  • Review context management: Instruct your agent to create, list, read, and search persistent review rules or learned patterns for your organization.
  • Engineering review analytics: Have your agent analyze review activity and search findings by repository, team, author, severity, security relevance, status, text, or date.

Troubleshooting

1. Why does Claude not use the Composio connector for Greptile?

The connector can show as connected, but Claude must use it in each Greptile conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Greptile again.

2. Why does Claude show an MCP server error before Greptile connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Greptile.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Greptile.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Greptile authorization link not work?

The Composio connector is one server. Your Greptile account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Greptile connection.
  • Composio creates a fresh Greptile authorization link.
  • Open that link in your browser and finish the Greptile sign-in.

4. Why do Greptile actions fail after they worked before?

The Greptile connection can expire or lose permission.

  • Ask Claude to inspect the Greptile connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Greptile account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Greptile.
  • If the action still fails with a permission error, check that the connected account has that permission in Greptile itself.

5. How do I switch to a different Greptile account?

Claude can manage the Greptile connection for you.

  • Ask Claude to disconnect or delete the current Greptile account.
  • Ask Claude to connect Greptile again.
  • Open the new Composio authorization link for Greptile.
  • Sign in with the other Greptile account in the browser.
  • After the account connects, ask Claude to retry the Greptile task.

6. Why is my Greptile connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Greptile connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Greptile tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Greptile.

FAQ

Frequently asked questions

With a standalone Greptile MCP server, the agents and LLMs can only access a fixed set of Greptile tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Greptile and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Greptile tools.

Yes, absolutely. You can configure which Greptile scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Greptile data and credentials are handled as safely as possible.
