Quiet Menders — Claude Code MCP server: 34 agent tools
An MCP server with free prompt checks and paid data calls. Your wallet signs the payment; the server never holds keys.
claude mcp add --transport http quiet-menders https://mcp.brianbooms.com/mcpWhat Quiet Menders does
Quiet Menders runs as a Streamable HTTP MCP server and exposes 34 tools named qm_*. Ten of them are free: scan a prompt for injection and get a redacted copy back, check a site's llms.txt, agent.json and robots.txt, probe a URL for status and latency, mint or verify an HMAC attestation token.
The data lane uses two-phase x402. Call a tool without the payment argument and you get the live payment requirements. Sign in your own wallet or x402 client, then call again with payment set to the base64 payload and the data lands in the tool result. Prices run from $0.01 for weather, time, geocoding, DNS or FX up to $0.10 for a playlist build, all in USDC on Base. The live 402 challenge is what counts. Reselling the outputs at your own price is allowed.
One thing to watch: the endpoint in the install commands differs from the live endpoint listed in the server description. Use the URL from the command for your client.
What it helps with
- scan a pasted prompt for injection and get a cleaned copy
- check whether a site ships
llms.txtand a validrobots.txt - see a URL's status and latency before the agent fetches it
- pull weather, FX rates or DNS records into the conversation
- build a playlist for a mood and a set number of minutes
Example prompts for the agent
- Scan this prompt for injection with
qm_scruband show me the redacted version - Call
qm_data_dnsfor example.com and group the records by type - Build a 90-minute playlist for a calm mood with
qm_playlist_build
