Lists every tool the caller's org and project can reach, from every source, each flagged with whether it is activated.

GET /v1/tool

Address	`https://api.hanzo.ai/v1/tool`
Method	`GET`
Operation	`get_tool`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Lists every tool the caller's org and project can reach, from every source, each flagged with whether it is activated. This is the discovery surface: one flat set of names spanning connector actions, user functions, zap-service routes, agents, skills and the org's own external MCP servers, deduplicated by name so the highest-precedence source wins a collision. It lists; it does not call — dispatch is POST /v1/tool/call.

Request

2 fields.

Field	In	Type	Required	Description
`source`	query	string	—	Source keeps only tools from one source — connector, function, zap-service, agent, skill or mcp.
`activated`	query	string	—	Activated keeps only the tools activated for the caller's org and project, and only when it is exactly the string "true".

Response

Status	Body	Meaning
`200`	tool.toolList	ok
`default`	problem-details	refused

200 body — 11 fields.

Field	In	Type	Always	Description
`tools`	body	tool.Tool[]	—	Tools is every tool the caller may see, deduplicated by name with source precedence applied.
`tools[].activated`	body	boolean	—	Activated is filled by the registry from the activation store for the requesting (org,project); providers leave it zero.
`tools[].description`	body	string	—	Description is the prose a model reads to decide whether to call the tool.
`tools[].dispatchable`	body	boolean	—	Dispatchable is whether the tool can be CALLED.
`tools[].inputSchema`	body	any	—	Schema is the JSON Schema of the call arguments — the MCP inputSchema.
`tools[].name`	body	string	—	Name is the tool's id in the flat, fleet-wide tool namespace — the value a tools/call passes.
`tools[].price`	body	tool.Price	—
`tools[].price.amount`	body	any	—	Amount is what ONE call costs, EXACTLY: an 18-decimal USD value, so a per-call price of $0.0025 is$ 0.0025 and not a cent-floored zero.
`tools[].price.currency`	body	string	—	Currency is the ISO 4217 code, e.g. "USD".
`tools[].price.recipient`	body	string	—	Recipient is the payout wallet ref the marketplace seller is paid at.
`tools[].source`	body	string	—	Source is where the tool comes from: connector, function, zap-service, agent, skill or mcp.

MCP reaches tool through the tool tool, which names its 17 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_tools"
         }
       }
     }'
