Ny Authority Debt MCP Server

ny-authority-debt

New York public authority debt issuance — which authority borrowed, for what project, on what terms, and when. Sourced from the four Authorities Budget Office datasets New York publishes on data.ny.gov. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1867+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

Coverage

Four authority classes, ~4,470 reported rows:

Each row is one authority's report for one fiscal year. Rows where issued_debt_obligations is N mean this authority issued nothing that year — the tools filter to Y so an authority's quiet year never looks like an issue with blank fields.

What this is not

• No secondary-market trade prices. This is primary issuance: what was sold and on what terms. Beyond that, most municipal bonds trade infrequently enough to have no current market price at all — what vendors sell as a muni "price" is usually an evaluated price, an estimate rather than a trade. A caller who assumes otherwise will read absence as "no trades happened".
• No CUSIPs. See below.
• New York only. California is covered by ca-debtwatch. For identifying one individual bond anywhere, use openfigi_search with marketSecDes: "Muni".

Two constraints that shaped the code

CUSIP is dropped deliberately. The State Authorities dataset carries a cusip_number column, populated on 1,295 rows with real 9-character CUSIPs. CUSIP identifiers are licensed by CUSIP Global Services, and that licence — not copyright in the underlying facts — is the binding constraint. The column is stripped before anything is returned, there is no CUSIP filter, and nothing is stored. Key on the issuer name here, and on FIGI via openfigi for an individual bond. Do not add it back.

EMMA is linked, never fetched. MSRB's terms are a contract accepted by using EMMA and they forbid building a database from their content. The official_statement_url this pack returns is a link New York itself published — often to a PDF hosted on emma.msrb.org, sometimes to the authority's own site — and it is passed straight through without being requested or parsed. emma_search_url is a composed search link, named for what it honestly is: the path returns 200, but the page is script-driven and we deliberately do not parse it, so it may not pre-fill the search.

Data sources

• New York State Open Data — https://data.ny.gov (Authorities Budget Office debt-issuance reporting)

Gotcha: Socrata catalog search federates across states

Querying another state's Socrata catalog (e.g. data.texas.gov) returns these same dataset ids, because the catalog API federates. Texas does not publish them. Always check metadata.domain on a catalog hit before attributing a dataset to a state — verified 2026-09-01 that all four report domain: data.ny.gov.

Quick Start

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

{
  "mcpServers": {
    "ny-authority-debt": {
      "url": "https://gateway.pipeworx.io/ny-authority-debt/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/ny-authority-debt/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 1867+ 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/ny_authority_debt_search \
  -H 'Content-Type: application/json' \
  -d '{"authority":"Dormitory","min_amount":100000000,"limit":3}'

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

Run it from npm

@pipeworx/mcp-ny-authority-debt is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/ny-authority-debt/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "ny-authority-debt": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-ny-authority-debt"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

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 Ny Authority Debt data" })

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