The G2X MCP server brings G2X, the intelligence layer for GovCon growth, to your own MCP client or agent, with the endpoints, transport and sign-in it needs.
| Endpoint | What it offers |
|---|---|
https://mcp.g2x.com/mcp | Every tool the signed-in account can use: research, documents and account actions such as watchlists, saved searches, pipelines and CRM |
https://mcp.g2x.com/mcp/research | Only the tools that read. Tools that change an account aren't listed and can't be called by name |
Both use the same sign-in, and every call runs as the signed-in G2X account.
The server speaks MCP over Streamable HTTP. Send JSON-RPC requests as POST with Content-Type: application/json and Accept: application/json, text/event-stream. The MCP handshake negotiates the protocol version.
The server is stateless: it doesn't issue a session ID, so don't depend on one. A GET to an endpoint answers 405.
tools/list and every tool call need a signed-in G2X account. Clients sign in with OAuth; see Authentication.
tools/list is the source of truth for tool names, input and output schemas and annotations. Read it when you connect instead of hardcoding names; see Tools and results.
