Install

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).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http osf 'https://gateway.pipeworx.io/osf/mcp'

mcp-osf

OSF (Open Science Framework, by the Center for Open Science) MCP.

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

Tools

ToolDescription
search_projectsOSF (Open Science Framework, by the Center for Open Science): search public research projects ("nodes") by title. Returns id, title, description, category, creation date, and tags. Keyless public data; the API can be slow.
get_projectOSF: fetch metadata for a single public research project (node) by its OSF id (e.g. "abc12"). Returns title, description, category, dates, tags, and public flag.
search_preprintsDEPRECATED ALIAS for osf_search_preprints — identical behavior, kept for existing callers. New callers should use osf_search_preprints.
osf_search_preprintsOSF: search public preprints by title (Open Science Framework, by the Center for Open Science). Returns id, title, description, publication date, DOI, and tags. Keyless public data; the API can be slow.

Quick Start

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

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

tools/list at https://gateway.pipeworx.io/osf/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/osf_search_projects \
  -H 'Content-Type: application/json' \
  -d '{"query":"climate change"}'

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-osf

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 Osf data" })

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

Frequently asked questions

What is Osf?

OSF (Open Science Framework, by the Center for Open Science) MCP.

How do I install Osf?

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

Does Osf need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is Osf open source?

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

Who maintains Osf?

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.
