Key features

  1. 01Search by term or case name
  2. 02List cases for a term
  3. 03Retrieve case facts and decisions
  4. 04View justice opinions and advocates
  5. 05Check oral-argument audio availability

Use cases

  1. 01Find a specific Supreme Court case
  2. 02Browse a term’s case list
  3. 03Research decisions and justice opinions

MCP support

The MCP server exposes tools for searching SCOTUS cases, listing cases by term, and retrieving case details. It can connect through a Pipeworx remote endpoint or local stdio.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Endpointhttps://gateway.pipeworx.io/oyez/mcp
Copy install command

Windsurf~/.codeium/windsurf/mcp_config.json

Run commands in a terminal; paste JSON into the client’s MCP config and restart. Servers that need sign-in will prompt on first connect.

From the project README

mcp-oyez

Oyez SCOTUS MCP.

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

Tools

ToolDescription
search_casesSearch US Supreme Court (SCOTUS) cases from Oyez by term year and/or case-name substring. Returns compact summaries with the question presented, description, and IDs for get_case. If neither term nor name is given, defaults to the most recent term. Keyless.
get_caseGet a full SCOTUS case from Oyez by term and docket number — question presented, facts, conclusion, decision (winning party, vote split, decision type), which justices were in the majority vs. dissent, advocates, and whether oral-argument audio exists. Keyless.
cases_by_termList the SCOTUS cases for a given term year from Oyez — compact summaries (name, docket, citation, short question, oyez_url). Use to browse a full term. Keyless.

Quick Start

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

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

tools/list at https://gateway.pipeworx.io/oyez/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/oyez_search_cases \
  -H 'Content-Type: application/json' \
  -d '{"name":"Harvard","limit":10}'

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-oyez

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 Oyez data" })

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

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
