evidentia-mcp
Model Context Protocol (MCP) server for Evidentia.
Exposes Evidentia's gap analysis, risk-statement generation, control explanation, OSCAL emit, and gap-diff surfaces to MCP-aware AI clients (Claude Desktop, Claude Code, ChatGPT Desktop, custom MCP clients).
Quick start
pip install evidentia[mcp]
# Run the server over stdio (the canonical MCP transport)
evidentia mcp serve
# Health check (validates SDK availability + reachable
# evidentia-core / evidentia-ai surfaces)
evidentia mcp doctor

All credential handling follows the same env-var-driven secret-handling protocol Evidentia uses everywhere — the MCP server NEVER accepts credentials in tool arguments.
Transport
v0.8.0 ships the stdio transport only (the most common + canonical MCP transport — used by Claude Desktop, Claude Code, and most other MCP clients). HTTP transport + Client ID Metadata Document (CIMD) richness defer to v0.8.1.
