Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Heaventree WHMCS MCP show me overdue invoices for this month"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Original, MIT-licensed WHMCS addon exposing documented local API tools, operational BI reports and guarded administration over Model Context Protocol. Upload one addon folder to WHMCS; no Docker, remote database login or WHMCS remote API IP allowlist.
Release candidate 0.1.0. Local protocol/security tests are provided. Production WHMCS staging acceptance and Maxer provider verification are separate gates. Exact parity with the encrypted paid addon is not yet verified; see coverage. The existing commercial addon and JOSH bridges are not modified by this build.
Default access is read-only. Write execution requires a write-scoped token, the addon write switch, and a five-minute administrator-approved request bound to the exact tool, parameters and token. Approvals are single-use; unknown execution outcomes require independent verification, not automatic retries.
Business data remains on the WHMCS server until an authorized MCP client reads it. That client's model provider may receive returned data: self-hosting the addon does not guarantee data stays on-server when using a cloud AI client. Responses redact credential-like fields; token/audit tables do not store raw customer response bodies. Deployers must handle customer data lawfully and restrict access appropriately.
PHP8.1+; no runtime Composer dependencies. Run php tests/run.php, node --test tests/bridge.test.mjs, and syntax-check every PHP file. Build an immutable ZIP with pwsh -NoProfile -File scripts/package.ps1. ZIP entries use / separators and include no secrets or vendor code.
Catalog regeneration: node scripts/generate-catalog.mjs /PATH/TO/OFFICIAL/WHMCS/developer-docs. The initial catalog uses documentation commit 2e75f454aa248b791948e14ad7b33fa9f0ded761. Regeneration is a reviewed build step, not runtime endpoint discovery; newly added operations default to write scope unless explicitly classified read-only.

The HubSpot MCP Server acts as a bridge that enables AI assistants and Large Language Models to securely interact with HubSpot CRM data through natural conversation, without requiring users to understand complex API structures. It provides read-only access to standard CRM objects (contacts, companies, deals, tickets, products, invoices, and more) and their associations, secured via OAuth 2.0, allowing AI agents to perform tasks like summarizing deals, fetching company updates, and looking up record changes.
