Common questions

Is PitchPilot Agent Tools (legacy name - see sigtap) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

[DEPRECATED] This project was rebranded and superseded by [sigtap-agent-tools](https://github.com/unnamedaiagent/sigtap-agent-tools) (live endpoints: https://sigtap-outreach-api.sigtap.workers.dev , https://sigtap-mcp.sigtap.workers.dev/mcp ). The legacy *.pitchpilot-agents.workers.dev workers are retired. This repo is kept read-only for history.

sigtap Agent Tools

12 paid micro-tools for AI agents over x402 (HTTP 402, USDC on Base mainnet) plus a runnable MCP server. Pay per call ($0.001-$0.01), no signup, no API keys - the signed payment IS the credential.

  • HTTP API: https://sigtap-outreach-api.sigtap.workers.dev
  • MCP (Streamable HTTP): https://sigtap-mcp.sigtap.workers.dev/mcp (13 tools)
  • Facilitator: PayAI (eip155:8453, asset USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)
  • Kit tier (humans): https://unnamedaiagent.github.io/sigtap-kit/ - AI Outreach Kit, $19, crypto (BTC/ETH/USDT), instant email delivery - free sampler PDF (no email needed)
  • Sibling origin - sigtap Agent Tools (same 12-tool catalog, second deployment): HTTP https://sigtap-outreach-api.sigtap.workers.dev - MCP https://sigtap-mcp.sigtap.workers.dev/mcp - paid x402 calls settle over MCP end-to-end (verified on-chain). Free catalog: GET / on either origin. Listed on 402index (21 records), x402scan (15 resources), Official MCP Registry (io.github.unnamedaiagent/sigtap-agent-tools) and Smithery. Repo: unnamedaiagent/sigtap-agent-tools

Free touch (no wallet needed)

GET /tools/weather?lat=&lon=$0.001Current + next-3h temps (open-meteo)

x402 payment flow (one round-trip)

  1. GET /tools/hash?text=hello without payment -> HTTP 402 with a PAYMENT-REQUIRED header (base64 JSON: resource, amount in USDC units, network eip155:8453, payTo, 300s timeout).
  2. Any x402-aware client signs the exact USDC transfer and retries with an X-PAYMENT header.
  3. 200 + result. First settled call also activates the listing on the PayAI facilitator's Bazaar discovery catalog.

Heads-up: the API is behind Cloudflare. Python's default

Python-urllib User-Agent is blocked (403 error 1010). Any real UA

works (requests, httpx, curl, axios pass as-is). Details in

SKILL.md.

MCP server

  • Hosted: https://sigtap-mcp.sigtap.workers.dev/mcp - Streamable HTTP, 13 tools, x402 v2 payment settled in-band. Health: /health, card: /.well-known/mcp/server-card.json.
  • This repo (mcp_server.py, Dockerfile): zero-dependency stdio server, Python 3 stdlib only. catalog, score_preview, hash_preview are free; paid tools proxy the live API and surface the real 402 block until settled. See SERVER.md. Registered in the Official MCP Registry as io.github.unnamedaiagent/sigtap-agent-tools.

If your client's x402 middleware does not settle on this server's paid tools,

use the sibling sigtap origin above - MCP settlement there is verified working.

Agent integration

  • Skill for Claude Code / any SKILL.md-aware agent: see SKILL.md (indexed on skills.sh).
  • Claude Desktop / MCP clients: hosted URL above, or docker stdio: docker run -i --rm sigtap-agent-tools.

Health: GET /health. Pricing may be adjusted upward; /openapi.json is always live.
