Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

mcp-idigbio

iDigBio biodiversity specimen MCP.

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

Tools

ToolDescription
search_specimensSearch ~150M digitized natural-history museum specimen records (plants, animals, fossils) from US collections via iDigBio. Filter by any combination of taxonomy and locality. At least one filter is required. Keyless.
get_specimenGet the full normalized record for a single iDigBio specimen by its uuid. e.g. uuid "0746b188-c390-4ab1-bd20-5489a9c6c33c" (a Puma concolor record). Keyless.
count_by_fieldGet taxonomic/geographic specimen counts grouped by a field (top values + counts) across iDigBio. Optionally scope the counts with taxonomy/locality filters. Keyless.

Quick Start

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

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

tools/list at https://gateway.pipeworx.io/idigbio/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/search_specimens \
  -H 'Content-Type: application/json' \
  -d '{"scientific_name":"puma concolor","limit":10}'

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-idigbio

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 Idigbio data" })

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

Frequently asked questions

What is Idigbio?

iDigBio biodiversity specimen MCP.

How do I install Idigbio?

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

Does Idigbio need an API key?

Yes. It expects PIPEWORX_API_KEY, which you set in its configuration.

Is Idigbio open source?

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

Who maintains Idigbio?

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.
