How to Set Up and Use Caido
The Caido MCP server connects AI assistants like Claude Code to the Caido web security proxy, enabling them to browse, analyze, and interact with captured HTTP traffic. It exposes over 64 tools covering request history search, replay session management, finding creation, fuzzing result access, sitemap browsing, intercept control, scope and project management, and race-condition testing. Security engineers and penetration testers use it to have AI assistants help analyze HTTP traffic, identify vulnerabilities, and automate repetitive testing tasks directly within their Caido workflow.
Prerequisites
- Caido installed and running (https://caido.io) — the proxy must be accessible at its configured URL
- A Personal Access Token generated in Caido at Settings > Developer > Personal Access Tokens
- The caido-mcp-server binary installed (via install script or GitHub Releases download)
- An MCP-compatible client such as Claude Code or Claude Desktop
Install the caido-mcp-server binary
Run the install script to download and install the MCP server binary for your platform. Pre-built binaries are available for macOS, Linux, and Windows in both amd64 and arm64 architectures.
curl -fsSL https://raw.githubusercontent.com/c0tton-fluff/caido-mcp-server/main/install.sh | bashGenerate a Caido Personal Access Token
In Caido, navigate to Settings > Developer > Personal Access Tokens and create a new token. Copy it — you will use it as the CAIDO_PAT environment variable.
Configure your MCP client
Add the caido-mcp-server to your MCP client configuration with the CAIDO_URL pointing to your Caido instance (default is http://127.0.0.1:8080) and your personal access token.
Alternative: authenticate via OAuth device flow
If you prefer not to use a PAT, authenticate interactively via the OAuth device flow. The token is saved to ~/.caido-mcp/token.json.
CAIDO_URL=http://localhost:8080 caido-mcp-server loginVerify the connection
Ask your AI assistant to list recent HTTP requests from Caido history. The server will query Caido's API and return results filtered by your active project.

Use these prompts to have Claude analyze HTTP traffic and assist with security testing through Caido.
- "Show me the last 20 HTTP requests captured by Caido for target.com"
- "Search Caido history for requests containing SQL keywords in the parameters"
- "Create a new replay session for the last login request and replay it with a modified Authorization header"
- "List all findings recorded in Caido for the current project"
- "Show me the sitemap of endpoints discovered for api.target.com"
- "Send 50 simultaneous requests to test for race conditions on the checkout endpoint"Troubleshooting Caido
Server returns 'connection refused' when connecting to Caido
Verify Caido is running and accessible at the URL set in CAIDO_URL (default http://127.0.0.1:8080). Open the Caido UI in a browser to confirm it is active before starting the MCP server.
Authentication fails with 'invalid token' error
Ensure CAIDO_PAT is set to a valid Personal Access Token from Caido's Settings > Developer > Personal Access Tokens. Tokens are project-scoped — make sure the active project in Caido matches what you expect to query.
Request history tools return no results
Caido stores traffic per project. Switch to the correct project in the Caido UI and ensure you have captured traffic for the target domain before querying. Use HTTPQL filters to narrow results: e.g. filter by req.host to scope to a specific domain.
