MCP call tool

Tag 7: the client sends the params of the MCP method; the server opens the proxy’s /tool/call-tool and relays exactly one channel response, the result or the MCP error, and the channel response finish.

The client opens this channel for one tool of the MCP server of the container, called. The server opens /tool/call-tool on the proxy with the params and relays its one answer.

• The request. The tag byte 7 followed by the params as JSON. Request states its form.
• The response. Exactly one channel response, the result or an MCP error, and the channel response finish. Response states the sequence.
• Every exchange is answered. An MCP error the container’s server returned, and the error the proxy sends for params that do not parse or a server it cannot reach, are relayed as the one channel response.
