@pipeworx/fca-register

UK Financial Conduct Authority Financial Services Register (register.fca.org.uk) — the public record of every FCA-regulated firm and individual: firm search, firm details by FRN, a firm's appointed representatives, and an individual's own public register record by IRN.

Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.

Tools

• fca_firm_search(q, type?) — search the register by name; type is one of firm (default), individual, fund.
• fca_firm_details(frn) — a firm's status, business type, and address by Firm Reference Number.
• fca_firm_representatives(frn) — a firm's appointed representatives by FRN. An empty list for a firm with none is a real answer, not a failure.
• fca_individual_lookup(irn) — a single individual's own public register record (name, current approved-function status) by Individual Reference Number. Looks up exactly one IRN; does not enumerate or list individuals.

Auth

No key needed from the caller: Pipeworx fronts one. The FCA ties each API key to a signup email and needs both on every request; a caller who wants to use their own can pass _apiKey as "<email>:<key>" (register free at https://register.fca.org.uk/Developer/s/registernewuser).

Data sources

• https://register.fca.org.uk/services/V0.1 — base URL. Auth via X-Auth-Email / X-Auth-Key headers, ~50 requests/10s per the FCA's own developer documentation.
  • GET /Search?q=<name>&type=firm|individual|fund
  • GET /Firm/{FRN}
  • GET /Firm/{FRN}/AR (appointed representatives)
  • GET /Individuals/{IRN}
• https://register.fca.org.uk/Developer/s/ — developer portal / signup.

UNVERIFIED beyond the no-key and garbage-key cases — no key exists on the fleet. Endpoint paths above are corroborated across multiple independent third-party client libraries (the fsrapiclient / financial_services_ register_api Python packages, CyborgFinance/FCARegisterLaravel) that all describe the same shapes, but this pack has never completed a successful authenticated call. Live-probed 2026-09-23 with a syntactically-valid but non-functional key: every endpoint answered with a real, on-brand JSON body ({"Success":"false", "Value not found"}, HTTP 404) rather than a DNS failure or a generic edge error — strong evidence the base URL and path shapes above are correct, just not proof of the populated/successful response shape. raw is included on every tool's response so a caller with a real key gets the untouched upstream payload even if a field name assumption here turns out stale.

Personal-data scope is deliberate: fca_individual_lookup exposes only the register's own single-record public fields for one IRN a caller already has. This pack ships no bulk/enumeration tool over individuals (no "list every approved person", no alphabet crawl) — do not add one without re-checking that boundary.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/fca-register/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 1683+ 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/fca_firm_search \
  -H 'Content-Type: application/json' \
  -d '{"q":"Barclays Bank","type":"firm"}'

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-fca-register

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 Fca Register data" })

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