ForgeMesh Utility Grid MCP server

ForgeMesh Utility Grid MCP

A ForgeMesh Labs product.

Search and use more than 400 practical APIs without loading hundreds of tools into your agent. Utility Grid exposes six compact MCP tools for OCR, image and audio processing, web extraction, math, conversions, geodata, and more. Catalog discovery is free; API execution is paid per call in USDC on Base through x402. No account or API key is required.

Rather than exposing one MCP tool per route (unmanageable at this scale and growing), this server exposes a handful of meta-tools: browse/search the live catalog, fetch a route's exact call spec, then call any route generically. New routes on the upstream service show up automatically — nothing here is hardcoded to today's catalog.

Quick start (Claude Desktop / Claude Code / any MCP client)

{
  "mcpServers": {
    "utility-grid": {
      "command": "npx",
      "args": ["-y", "@forgemeshlabs/utility-grid-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "0x..."
      }
    }
  }
}

WALLETPRIVATEKEY is only needed for the 3 paid tools. Discovery works with no wallet at all — skip the env block entirely to browse and plan calls for free.

Tools

Categories in the catalog (illustrative, not exhaustive)

geo (airports, zip codes, geocoding, weather), lookups (dictionary, Bible, country info, holidays), math (statistics, matrices, equations, geometry), utilities (QR codes, hashing, UUIDs, phone parsing), vision (OCR, image captioning, background removal), audio (TTS, transcription, format conversion), time (timezones, cron, sun/moon), space (NASA APOD, asteroids, solar weather), web (content extraction, robots.txt/Content-Signal checks), registry (fleet catalog, daily spotlight), documents (PDF handling), text (language detection, readability), economy (fx rates, financial calculators), science, developer, domains, ai, and fun (fortunes, chess, trivia).

Call list_capabilities with no arguments for the live, current breakdown — the catalog grows over time and this README will drift; the tool won't.

Typical flow

1. search_capabilities({ query: "background removal" }) — free, finds /remove-background
2. getendpointspec({ path: "remove-background" }) — free, shows the exact input schema and price
3. callendpoint({ path: "remove-background", body: { imageurl: "https://..." } }) — paid, does the x402 dance and returns the result

Or skip straight to call_endpoint if you already know the route and its input shape.

How payment works

No signup, no API key, no subscription. callendpoint, daily402, and agentservicedirectory each trigger the same flow: the first request returns an HTTP 402 challenge, this MCP server signs a USDC payment authorization (EIP-3009) on Base and retries, and the result lands in the same response — including settlement details under _payment when available.
