SignalHarness.ai is an MCP server with 3 tools an agent can call, among them get_service, invoke_service, list_services. It answers at https://signalharness.ai/api/agent/services/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
330 production AI-agent services for data, validation, AI, crypto, and x402 pay-per-use.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_service | Inspect one enabled public SignalHarness service before invoking it. Use an exact service_id returned by list_services. This free, read-only call returns the canonical description, input and output schemas, price, endpoint, and supported pa Inputs: service_id |
invoke_service | Run exactly one enabled public SignalHarness service with caller-supplied input. Call get_service first and validate input against its input_schema. An unpaid call returns the canonical x402 V2 PAYMENT-REQUIRED challenge plus the equivalent Inputs: service_id, input, request_id, idempotency_key |
list_services | Discover the currently enabled public SignalHarness service catalog before choosing a service. This free, read-only call takes no arguments and returns a compact service array with canonical IDs, descriptions, prices, and supported payment |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://signalharness.ai/api/agent/services/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 21 September 2026. The tools are exactly what the server returned; nothing on this page
