Description from the maker (original English)
Discover and call 400+ practical APIs through seven MCP tools with free search and x402 payments.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

*A ForgeMesh Labs product.*
Search and use more than 400 practical APIs without loading hundreds of tools into your agent. Utility Grid exposes seven 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.
{
"mcpServers": { "utility-grid": { "command": "npx", "args": ["-y", "@forgemeshlabs/utility-grid-mcp"], "env": { "WALLET_PRIVATE_KEY": "0x..." } } } }
WALLET_PRIVATE_KEY 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.
| Tool | Cost | What it does |
|---|---|---|
list_tools | free | Every route with its live price plus a per-category summary — a plain fetch of GET /menu, no wallet |
list_capabilities | free | Category overview with route counts, or every route in one category |
search_capabilities | free | Keyword search across every route's path, id, and description |
get_endpoint_spec | free | A route's exact price, input schema, and worked request/response examples |
call_endpoint | $0.005-$0.05 | Call any route by path + JSON body — handles the x402 payment flow automatically |
daily_402 | $0.005 | The Daily 402: one featured endpoint from the whole ForgeMesh fleet, rotated by UTC date |
agent_service_directory | $0.05 | Registry of every ForgeMesh x402 service — category, route count, price range |
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.
search_capabilities({ query: "background removal" }) — free, finds /remove-backgroundget_endpoint_spec({ path: "remove-background" }) — free, shows the exact input schema and pricecall_endpoint({ path: "remove-background", body: { image_url: "https://..." } }) — paid, does the x402 dance and returns the resultOr skip straight to call_endpoint if you already know the route and its input shape.
Node.js 20+. Paid tools need WALLET_PRIVATE_KEY: use a dedicated, low-balance Base wallet funded with USDC. The server refuses to sign for any payee other than the two Utility Grid wallets, any network other than Base mainnet, any asset other than USDC, or any amount over the cap ($0.05 per call, $10 per session). The env vars X402_MAX_PRICE_USD and X402_SESSION_BUDGET_USD can only lower those caps. Requests are same-origin, time out after 60 seconds, are capped at 2 MB, and never follow redirects. Tool results are returned wrapped as { source, untrusted, content }: the content is remote data, not instructions.
No signup, no API key, no subscription. call_endpoint, daily_402, and agent_service_directory 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.
Prefer raw HTTP? The full agent-readable surface:
https://x402.forgemesh.io/llms.txt — one-page summary for agentshttps://x402.forgemesh.io/openapi.json — OpenAPI 3.1 with x402 payment metadata, full input schemas, and worked examples for every route (this is what list_capabilities/search_capabilities/get_endpoint_spec read from, live, every call)https://x402.forgemesh.io/.well-known/x402.json — x402 discovery manifestlist_tools is a plain fetch of GET https://x402.forgemesh.io/menu. ForgeMesh attaches one disclosed Lulu Ads card to that free response server-side, as a plain labelled data field — never text the model could read as an instruction:
"sponsored": { "label": "Sponsored", "text": "...", "url": "https://..." }
This package ships no ad credentials and makes no calls to the ads network; it passes the field through untouched. Paid tools never carry a card. Strip it with delete result.sponsored.
Do I need an account or API key? No. x402 payments are the only credential, and only for the 3 paid tools.
What chain and token? USDC on Base mainnet (eip155:8453).
Will this break when the upstream catalog changes? No — list_capabilities, search_capabilities, and get_endpoint_spec all read /openapi.json live (cached in-memory for 5 minutes). call_endpoint never needs a hardcoded schema at all; it just forwards your JSON body.
