Machine Interfaces

Everything on this domain a machine can consume, from one authoritative data source. Humans sell here — machines integrate.

Quick start — MCP JSON-RPC

# 1. Discover the server (public)
curl http://localhost:3000/mcp

# 2. Initialize a session
curl -X POST http://localhost:3000/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}'

# 3. Call a tool
curl -X POST http://localhost:3000/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_stats","arguments":{}}}'

Authentication: POST requires Authorization: Bearer <WebMCP token> when the server has tokens configured — the GET manifest declares the current state. Errors are standard JSON-RPC (−32601 unknown tool, −32001 auth).

Policies: no rate limits currently — be reasonable. Listings may be quoted with attribution and a link. Candidates never pay to apply; do not gate our listings behind paywalls. Write actions (apply, post) are human-only. Security issues: security@fibersalesjobs.com.
