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

Tool surface

Tool	Maps to	Auth
gap_analyze	evidentia_core.gap_analyzer	none (read-only)
risk_generate	evidentia_ai.risk_statements	optional API key (LiteLLM env vars)
explain_control	evidentia_ai.explain	optional API key
oscal_emit	evidentia_core.oscal.exporter	optional Sigstore identity (env-driven)
gap_diff	evidentia_core.gap_analyzer.diff	none
collect_aws	evidentia_collectors.aws	provider creds (env-driven)
collect_github	evidentia_collectors.github	provider creds
collect_jira	evidentia_collectors.jira	provider creds

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.
