The Metis Fca Handbook AI Harness MCP server

Metis FCA Handbook AI Harness — MCP Server

<!-- mcp-name: io.github.99blakeD99/the-metis-fca-handbook-ai-harness-mcp -->

An MCP (Model Context Protocol) server that integrates the Metis FCA Handbook AI Harness into your AI workflow. MCP is supported by Claude, OpenAI, Gemini, and most desktop/IDE MCP clients (Cursor, Windsurf, Cline, and others) — this README uses Claude Code and Claude Desktop as fully worked examples; adjust the configuration steps to fit your own client.

Tools

evaluatefcahandbook_applicability

Evaluate which FCA Handbook entries apply to an entity, via the Metis FCA Handbook AI Harness. One-shot: no session, no conversation state. Supports quick mode (60-120 seconds, default) and full mode (longer, more detailed). Returns a compliance report with verbatim citations, gaps, and refinement suggestions.

Why choose The Metis FCA Handbook AI Harness?

• Efficiency Multiplies effectiveness of compliance advice. Saves £80+ in token fees per Harness run.

• Deals with "Hard Problem", in which LLMs' token incentives prioritise training data so results are unreliable.

• Verbatim citations Quotes verbatim entries from the FCA Handbook. Other AI systems struggle to do this.

• Matches real-world need You do not have to start off knowing which sections you are looking for. Carries out structured searches across all 33,000+ FCA Handbook entries.

• Secure Design Harness compartmentalisation, one-shot structure, and statelessness fits natively with emerging AI agent security standards such as OWASP Top 10 for Agentic Applications 2026.

• AI Accessible Integrates easily with AI workflows and agents. Your LLM can use it as a tool.

Design Principles

The Harness is built on proven principles:

• Stateless — Each request is independent; no session coupling
• One-shot — Complete analysis in a single call; no multi-turn state
• Clear contract — Explicit input/output schemas for easy integration
• Hosted — Single canonical source; no version drift or stale data

Use Cases

Compliance AI Platforms

Embed FCA reasoning as a service within your compliance platform. Users ask natural-language questions; your platform calls the Harness and presents structured reasoning.

AI Agent Workflows

Agents building compliance workflows can include FCA Handbook reasoning as a composed tool—no external API calls, just MCP configuration.

Compliance Review Automation

Integrate into document review or due-diligence pipelines. Automatically screen new rules against FCA applicability.

For Regulatory Screening

FS firms screening MCP servers will find:

• Simple model: Stateless, no hidden state, no background jobs
• Clear contract: Explicit input schema, output schema, error modes
• Transparent updates: Version pinning; no automatic upgrades
• Single point of failure: If the Harness is down, it is obvious; no cascading config issues
• Audit-friendly: All calls logged centrally, not distributed
