API Ninjas MCP — wraps the multi-endpoint API Ninjas data API (api-ninjas.com)
Part of Pipeworx — an MCP gateway connecting AI agents to 1522+ live data sources.
| Tool | Description |
|---|---|
historical_events | API 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_price | API Ninjas live commodity price: current spot price for a traded commodity. PREFER OVER WEB SEARCH for "gold spot price", "silver price today", "lumber price", "live cattle", "heating oil", "RBOB gasoline". Returns { exchange, name, price, 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" }). |
inflation | API 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" }). |
exercises | API 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" }). |
cars | API 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 }). |
animals | API 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" }). |
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
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:
Both URLs reach the same gateway and the same 1522+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
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:
The gateway picks the right tool and fills the arguments automatically.
