Crowntowncompost MCP

crowntowncompost-mcp

MCP server for the Crown Town Compost customer portal — check your pickups, invoices, and upcoming collection days, skip a service, report a missed pickup, and update your account, all in natural language.

Developed and maintained by AI (Claude Code). Use at your own discretion.

What it talks to

crowntowncompost.com is a marketing site with no customer data. Everything lives at `portal.crowntowncompost.com`, a Django app (a white-labeled StopSuite hauler platform). This server authenticates server-side with a session cookie you already hold, or with your own portal username and password — a normal form login that returns one — and reads the same pages and JSON endpoints the website uses. No browser extension, no bot-wall workaround, no third-party service in the middle.

Install

npm install -g crowntowncompost-mcp

Then add it to your MCP host. Two configurations work — supply either a session cookie you already hold (nothing else needed), or the login pair so the server can mint one:

{

"mcpServers": { "crowntowncompost": { "command": "npx", "args": ["-y", "crowntowncompost-mcp"], "env": { "CROWNTOWN_USERNAME": "you@example.com", "CROWNTOWN_PASSWORD": "your-portal-password" } } } }

To use a session cookie instead, set CROWNTOWN_SESSION_COOKIE to a Cookie header value from a signed-in browser session (sessionid=…; csrftoken=…) and leave the username and password unset. The portal login is then never run, and no password is stored anywhere.

Setting both is also valid, and is the most robust configuration: the cookie is used first, and when the portal eventually expires it the login quietly mints a replacement. With a cookie alone, an expired session is reported as expired — the server says so plainly rather than claiming nothing is configured.

Locally you can instead copy .env.example to .env. The server boots without credentials (so a host's install-time probe succeeds); the configuration error surfaces on the first tool call.

Tools

Reads

Writes (all confirmation-gated)

Every mutating tool asks you to confirm before it writes anything. A client that can show a confirmation prompt (Claude Code) gets that prompt (unless MCP_CONFIRM_ELICITATION=off). Elsewhere (claude.ai, Claude Desktop) the first call sends nothing and returns status: "confirmation-required" with a preview of exactly what would be sent plus a confirmToken; only a repeat call with the same arguments and that token proceeds. The token works once, expires, and is refused (DRAFT_CHANGED) if what would be sent changed in between — including values the tool reads first, such as the account form crowntown_update_account re-saves or the reply-to email/phone the support form pre-fills. Where a re-read can prove the change stuck (skips, account updates) the tool re-reads and reports verified; where it can't (support messages, missed-pickup reports) it says so rather than claiming success.

Confirmations

Payments are deliberately out of scope — crowntown_list_invoices returns the hosted invoice URL for you to open in a browser.

Without the MCP

The skills/crowntown-portal skill does the same things with curl in a shell — useful in scripts or on a machine where this server isn't installed. It documents the Django CSRF handshake, both JSON endpoints, and every write's field list.

Development

npm install

npm run build npm test

Tests mock the network — no credentials needed and nothing hits the live portal. tests/server-boot.test.ts spawns the real built artifacts (the npm bin and the bundle, the latter without node_modules) and runs the MCP handshake against them.

Endpoint shapes are documented in docs/CROWNTOWN-API.md, including which parts are live-verified and which are not.
