AI

ai: 3 operations.

Also for this capability: API · CLI · MCP · SDKs

ai: 3 operations. Name one in "op" and pass that operation's own arguments in "input". describe returns an operation's input schema.

Tool	`ai`
Address	`https://api.hanzo.ai/v1/mcp`
Method	`tools/call` (JSON-RPC 2.0)
Arguments	2, 1 required
Operation	`GET /v1/ai/limits` · `GET /v1/ai/mcp/tools`
Product	ai

Arguments

Field	Type	Required	Default	Values	Description
`input`	`object`	—	—	—	arguments for the chosen op
`op`	`string`	yes	—	—	—

tools/list declares a type, a description, which fields are required and an enumerated value set for each field and nothing further, and every column above is MCP's own. This tool takes an operation name and that operation's arguments, so what the document constrains is what goes inside input, field by field, on the operation you name — ask describe for that. A — means MCP does not constrain the field.

Call it

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. This call carries exactly the arguments the operation requires, so it is the smallest one that can run.

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

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one MCP answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.

The operation behind it

ai dispatches to 3 operations. 2 of them MCP names exactly as the document ids them, and those are below; for the rest MCP has its own verb, which describe resolves.

Operation	Route	Product	Summary
`aiLimits`	`GET /v1/ai/limits`	ai	Reads the caller's plan usage: for each class of model the plan includes, the share used of the billing period and of its short window, who pays for the next request, and whether the caller is in limited mode and why; the share used of the session and the day; and the ways on.
`aiMCPTools`	`GET /v1/ai/mcp/tools`	ai	Reports what THIS PROCESS's MCP server carries: how many tools its own registry projects, optionally their names, and which subsystems this process composed.

The same capability over plain HTTP is in the ai API reference, on https://api.hanzo.ai.
