Client registration. Clients can register themselves with dynamic client registration and sign in with the server URL alone. See Authentication.
The research endpoint. https://mcp.g2x.com/mcp/research offers only the tools that read. Tools that change an account aren't listed there and can't be called by name.
Whole documents. g2x_opportunity_attachment_text returns the complete text of an opportunity document in Markdown or JSON, in exact parts with the document's size and checksum. g2x_opportunity_documents lists what is on file without starting anything; g2x_prepare_opportunity_documents prepares documents for analysis.
Usage. g2x_usage reads how much of the account's G2X usage is used this session and this week, and when each resets. A call past the account's usage answers 429 with the time it resets.
Market questions. g2x_query filters and counts procurement records, totals award amounts, and saves larger answers as a workbook to download.
Account actions. Watchlists, saved searches, pipelines and G2X CRM records can be read and updated from an agent.
