FAA Regulations MCP — US Federal Aviation Regulations (14 CFR, 'FARs').

Part of Pipeworx — an MCP gateway connecting AI agents to 1679+ live data sources.

Tools

Tool	Description
faa_regulation	Get the full text of one Federal Aviation Regulation (FAR) — a US FAA / aviation regulation codified in 14 CFR — by its citation. Returns the exact regulatory wording currently in force. Answers "what does FAR 91.113 say", "what is the FAA regulation for X", "does the FAA require X", "read 14 CFR 107.29", "the FAA right-of-way rule". Forgiving citation input: "91.113", "14 CFR 91.113", "FAR 91.113", "§91.113", even "91.113(b)" (paragraph stripped to the section). Covers 14 CFR part 91 general operating & flight rules, part 121 airline/scheduled operations, part 135 commuter & on-demand, part 107 small unmanned aircraft (drone) rules, part 61 pilot/airman certification, part 43 maintenance, part 145 repair stations, part 25 aircraft airworthiness — the whole of Title 14 (aviation, aircraft, airspace, pilots). Pass a whole part (e.g. "91" or "107") to get that part's section list. Example: faa_regulation({ citation: "91.113" }) -> right-of-way rules; faa_regulation({ citation: "FAR 107.29" }) -> drone operation at night. Keyless.
faa_search	Keyword search across the Federal Aviation Regulations — US FAA / aviation rules in 14 CFR. Answers "what FAA regulations cover X", "the aviation rule / FAR about X", "find the FAA regulation for X". Great for topics: right-of-way, VFR/IFR flight rules, minimum safe altitudes, drone / small unmanned aircraft operations, remote pilot certification, airline operating requirements, pilot certification and medical, aircraft airworthiness, maintenance and repair stations, airspace, TFRs. Returns matching Federal Aviation Regulations with citation (14 CFR / FAR), heading, excerpt, and source URL. Note: the CFR text uses "unmanned aircraft", not "drone" — search "unmanned aircraft night" for drone-at-night rules. Example: faa_search({ query: "unmanned aircraft night" }); faa_search({ query: "right-of-way rules", limit: 15 }). Keyless.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/faa-regulations/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 1679+ 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/faa_regulation \
  -H 'Content-Type: application/json' \
  -d '{"citation":"91.113"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/faa_regulation. 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": {
    "faa-regulations": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-faa-regulations"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-faa-regulations

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 Faa Regulations data" })

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