Create mcp

Speaks MCP over streamable HTTP for one of the org's MCP servers, named by its id: tools/list answers the tools of it an admin of the org activated, and tools/call calls one.

Method	`POST`
Operation	`post_agent_mcp_by_server`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Speaks MCP over streamable HTTP for one of the org's MCP servers, named by its id: tools/list answers the tools of it an admin of the org activated, and tools/call calls one. The server's address and credential never reach the run: the tool plane adds the credential and dials the server.

The caller is a coding run, not a tenant: the request carries the run's ticket in X-Hanzo-Run and no bearer. A request without a live ticket is 401, and a server the run's kit did not carry when it started is 403. A run has at most four requests in flight here and twenty in a burst, then one a second; a request past that is 429 with Retry-After.

MCP reaches agent through the agent tool, which names its 38 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_agents"
         }
       }
     }'
