Archway Advisory Group — MCP Server

Three governance tools exposed via the Model Context Protocol, deployed on Cloudflare Workers.

MCP Endpoint: https://archway-mcp.<YOUR_SUBDOMAIN>.workers.dev/mcp

Tools

archway-governance-diagnostic

Structured governance posture assessment. Scores maturity across board oversight, committee structure, documentation, and control environment — benchmarked against NYSE 303A, NASDAQ 5600, ISS 2026, Glass Lewis 2026, and NACD standards. Returns tier classification, domain findings, and engagement recommendations with fixed-fee pricing.

archway-engagement-scoping

Converts a diagnostic result (or direct request) into a scoped, priced engagement. Produces bounded scope, deliverable list, timeline, and fixed-fee pricing across all Archway service lines.

archway-rd-risk-screener

R&D tax credit documentation exposure screening. Assesses Four-Part Test substantiation, contemporaneous documentation practices, and IRS examination readiness. Includes regulatory boundary disclaimer.

Local Testing with Claude Desktop

Add to your Claude Desktop MCP config (claude_desktop_config.json):

      "url": "http://localhost:8787/mcp"
    }
  }
}

  }
}

Architecture

• Runtime: Cloudflare Workers (Durable Objects for MCP session state)

• Logic: Fully deterministic — no AI API calls. Scoring algorithms, pricing rules, and risk assessment run as pure functions.

• Cost: Effectively zero at expected volume (Workers free tier: 100K requests/day)

• Transport: Streamable HTTP (MCP standard), handled by McpAgent SDK
