• Durable Object-backed auth state with encrypted token storage.
• Company mode and practice mode support from one codebase.
• Broad read-only accounting and operational tool surface for analysis workflows.

• Capability mapping: Project/freeagent-mcp-implementation/capability-matrix.md

Architecture At A Glance

• Connector setup flow: /authorize -> FreeAgent consent -> /callback -> OAuth completion -> /mcp.
• Durable Objects:
• MCP_OBJECT for MCP session/runtime behavior.
• AUTH_STORE for principal auth records and pending OAuth handoff state.
• Deployment modes:
• company for direct single-company access.
• practice for practice dashboard plus client switching.

Endpoints

• MCP: https://..workers.dev/mcp
• Health: https://..workers.dev/health
• OAuth authorize: https://..workers.dev/authorize
• OAuth callback: https://..workers.dev/callback

Quickstart

Prerequisites:

• Node.js 20+
• Cloudflare account with Wrangler auth
• FreeAgent OAuth app with callback set to https://..workers.dev/callback

Install and run locally:

npm install
cp .dev.vars.example .dev.vars
npm run dev

Validation commands:

npm run type-check
npm run test
curl -i http://localhost:8787/health

Deploy

Set secrets once per environment:

npx wrangler secret put FREEAGENT_CLIENT_ID
npx wrangler secret put FREEAGENT_CLIENT_SECRET
npx wrangler secret put TOKEN_ENCRYPTION_KEY

Deploy:

npx wrangler deploy

Company Smoke Test

After deployment, run a repeatable company-mode smoke test:

npm run smoke:company -- https://..workers.dev/mcp

The script will:

• dynamically register an OAuth client
• print a browser authorization URL
• wait for the local callback on http://127.0.0.1:8090/callback
• run a small MCP smoke suite after auth completes

If You Are An LLM Agent

When helping users set up this repo, follow this exact order:

1. Install dependencies with npm install.
2. Copy .dev.vars.example to .dev.vars.
3. Ask the user to provide values for FREEAGENT_CLIENT_ID, FREEAGENT_CLIENT_SECRET, and TOKEN_ENCRYPTION_KEY.
4. Run npm run type-check and npm run test before starting dev or deploy steps.
5. Start local dev with npm run dev.
6. For deployment, ensure Wrangler auth works, then run npx wrangler deploy.

Rules for LLM agents:

• Never invent or hardcode credentials.
• Never commit .dev.vars, real secrets, or account-specific deployment values.
• Keep wrangler.jsonc placeholders intact in public branches.
• If account-specific config is temporarily needed for testing, keep it out of the public branch or restore placeholders before publishing.

Connect From Claude Or ChatGPT

1. Add your MCP URL in client settings:

https://..workers.dev/mcp

1. Complete FreeAgent consent in the browser.
2. In chat, run auth_status or get_company.
3. In practice mode, use list_clients and switch_client to choose an active client.
4. Run read-only tools.

Known Limitations

• Practice-mode end-to-end validation depends on having a FreeAgent practice sandbox or real practice environment.
• Some FreeAgent endpoints may behave differently depending on permission level, account type, or enabled product features.
• This project is intentionally read-only for safety.
