pacer-mcp

🪦 RETIRED. This standalone PAT-over-stdio server no longer reaches the Pacer API. Every tool returns a notice to switch to the in-process ("inline") Pacer MCP connector built into core, offered as the hosted "Pacer" connector on claude.ai / Claude Cowork (tools appear as mcp__…Pacer__…). The standalone binary called the API over the network at portal.pacerrev.io, which now redirects unauthenticated API calls to an HTML login page; the in-process connector dispatches to the same /api/v1 handlers with no network hop and can't drift from the API host. Remove this server from your MCP client config. The setup and tool docs below are kept for historical reference only.

An MCP server that exposes pacer/core API endpoints as native tools for Claude Code (and any other MCP-aware client). One binary, stdio transport, no fuss.

Install

macOS (Homebrew)

brew install STR-Consulting/tap/pacer-mcp

Windows (Scoop)

scoop bucket add pacer https://github.com/STR-Consulting/scoop-bucket
scoop install pacer-mcp

Linux (binary tarball)

For server/automation use. Replace <version> and pick amd64 or arm64:

curl -fsSL https://github.com/STR-Consulting/mcp/releases/latest/download/pacer-mcp_<version>_linux_amd64.tar.gz | tar -xz
sudo install pacer-mcp /usr/local/bin/

Or use the OCI image: ghcr.io/str-consulting/pacer-mcp:latest (linux/amd64 + linux/arm64).

From source

go install github.com/STR-Consulting/pacer-mcp@latest

Setup

Add to your MCP config (e.g. .mcp.json in your project or your Claude Code user config):

{
  "mcpServers": {
    "pacer": {
      "command": "pacer-mcp",
      "env": {
        "PACER_CORE_URL": "https://portal.pacerrev.io",
        "PACER_CORE_TOKEN": "pat_..."
      }
    }
  }
}

Run health_check after install to confirm the server can reach core.

PATs are minted by a core admin via pacer pat create --user <email> --label <name>; they require an employee-or-higher role and are sent as Authorization: Bearer pat_....

Tools

Each tool's full description (caveats, when to use, args) is returned to the MCP client at registration time — agents see them at tool-selection time. The list below is a quick index.

Releases are automated — push a v* tag and GitHub Actions builds darwin-arm64, windows-amd64, and linux-{amd64,arm64} binaries (plus a ghcr.io/str-consulting/pacer-mcp OCI image), then updates the Homebrew tap and Scoop bucket and publishes to the MCP Registry.
