briefcase.mcp

Terminal window
pip install briefcase-ai[mcp]

Exposes safe SDK operations to MCP-capable clients (Cursor, Claude Code, Codex, Replit). Run with the briefcase-mcp console script or python -m briefcase.mcp. The mcp extra installs mcp>=1.2,<2. mcp 2.0 removed mcp.server.fastmcp, which this module is built on.

build_server(), main()

from briefcase.mcp import build_server, main


server = build_server()    # returns a FastMCP server
# main() is the entry point used by the briefcase-mcp console script
build_server() -> FastMCP
main() -> None

Tools exposed to MCP clients:

sanitize_text(text) -> {"sanitized", "redactions"}                 # wraps briefcase.sanitize
estimate_cost(model, input_tokens, output_tokens)                 # wraps briefcase.cost
    -> {"model", "input_cost", "output_cost", "total_cost"}
analyze_drift(outputs: list[str])                                  # wraps briefcase.drift
    -> {"consistency_score", "agreement_rate", "consensus_output", "status"}
how_to(topic="") -> str                                            # usage guidance

The server also exposes a briefcase://llms-full.txt resource with the full usage guide.
