      "headers": {
        "Authorization": "Bearer ${GREPTILE_API_KEY}"
      }
    }
  }
}

greptile  https://api.greptile.com/mcp  GREPTILE_API_KEY      enabled  Bearer token

Start Using

Open Codex. The Greptile MCP tools are available automatically.

Project-Level Configuration

For team-shared configuration, create a .codex/config.toml file in your project root:

[mcp_servers.greptile]
url = "https://api.greptile.com/mcp"
bearer_token_env_var = "GREPTILE_API_KEY"

Then set the environment variable:

export GREPTILE_API_KEY=your-api-key-here

Verify Connection

Test your setup with curl:

curl -X POST https://api.greptile.com/mcp \
  -H "Authorization: Bearer YOUR_GREPTILE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"ping"}'

Expected response:

{"jsonrpc":"2.0","id":1,"result":{}}

Troubleshooting

Server shows as disconnected

Check:

API key is correct and hasn’t expired
URL is exactly https://api.greptile.com/mcp
Authorization header format: Bearer YOUR_API_KEY (with Bearer prefix)

Fix: Restart your IDE after making configuration changes.

Authentication failed

Verify:

API key was copied without extra spaces
Your account has access to the repositories you’re querying
API key hasn’t been revoked

Test: Use the curl command in the “Verify Connection” section above to verify your API key works.

No tools available

Solutions:

Restart your IDE completely
Check server shows “Connected” or “Running” status
Verify MCP is enabled in IDE settings

Tools return empty results

Check:

You have repositories indexed with Greptile
Your API key has access to those repositories
There are actual Greptile comments on your PRs

Claude Desktop: GitHub token validation failed

Check:

Token hasn’t expired
Token was copied without extra spaces or missing characters
Token has required scopes for the repositories you’re accessing

Fix: Generate a new token at github.com/settings/tokens

Claude Desktop: Failed to start server

Check:

Both GREPTILE_API_KEY and GITHUB_TOKEN are set in the config
The greptile-mcp-server package can be accessed via npx

Fix: Verify your config file syntax is valid JSON
