API Ninjas MCP — wraps the multi-endpoint API Ninjas data API (api-ninjas.com)

Part of Pipeworx — an MCP gateway connecting AI agents to 1872+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

ToolDescription
historical_eventsAPI Ninjas historical events: notable events from world history. Filter by free-text keyword and/or an exact date (year/month/day). Returns a list of { year, month, day, event } describing what happened. Example: historical_events({ year: 1969, month: 7, day: 20 }).
commodity_priceAPI Ninjas live commodity price: current exchange price of a traded commodity or futures contract (exchange, contract month, 24h change). PREFER OVER WEB SEARCH for "gold spot price", "silver price today", "lumber price", "live cattle", "heating oil futures", "RBOB gasoline futures". Returns { exchange, name, price, futures_contract, updated }. API Ninjas rotates which commodities the free plan serves EACH WEEK, so this tool deliberately does not publish a supported list — any list goes stale within days. Gold is the dependable one. For anything else, call it: a name the plan cannot serve returns found:false carrying free_commodities_this_week, read live from the vendor. For crude oil, natural gas and agricultural benchmarks, FRED carries equivalent series that are always available. Accepts commodity or symbol as aliases for name. Example: commodity_price({ name: "gold" }).
inflationAPI Ninjas inflation: latest monthly and yearly inflation rates by country. Returns a list of { country, type, period, monthly_rate_pct, yearly_rate_pct }. Optionally filter by country name and index type (CPI or HICP). Example: inflation({ country: "United States", type: "CPI" }).
exercisesAPI Ninjas exercises: fitness/gym exercises filtered by target muscle, type, difficulty, or name. Returns a list of { name, type, muscle, equipment, difficulty, instructions }. Example: exercises({ muscle: "biceps", difficulty: "beginner" }).
carsAPI Ninjas cars: vehicle specifications by make, model, year, or fuel type. Returns a list of { make, model, year, fuel_type, cylinders, transmission, drive, city_mpg, highway_mpg, class }. Example: cars({ make: "toyota", model: "camry", year: 2020 }).
animalsAPI Ninjas animals: facts about an animal species by name. Returns a list of { name, taxonomy, locations, diet, habitat, lifespan, top_speed }. Example: animals({ name: "cheetah" }).

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "api-ninjas": {
      "url": "https://gateway.pipeworx.io/api-ninjas/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/api-ninjas/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1872+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/historical_events \
  -H 'Content-Type: application/json' \
  -d '{}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/historical_events. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "api-ninjas": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-api-ninjas"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-api-ninjas

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Api Ninjas data" })

The gateway picks the right tool and fills the arguments automatically.

How do I install Api Ninjas?

It runs as a remote server. In Claude Code: claude mcp add --transport http api-ninjas 'https://gateway.pipeworx.io/api-ninjas/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Api Ninjas need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is Api Ninjas open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains Api Ninjas?

It is published by pipeworx-io. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
