Tools

Link a tool to an agent

Link a tool to an agent so the agent can call that tool during conversations. The relationship is many-to-many: a tool can be linked to many agents and an agent can have many tools. The response returns a link record whose id is the link_id — keep it, since it is how you later remove the link via DELETE /api/ext/tool/unlink/{link_id}. Authenticated with your API key.

Request fields

Link target

tool_id is the tool to attach (from GET /api/ext/tool or the create-tool response). agent_id is the agent to attach it to (from GET /api/ext/agent). Both must belong to the project the API key is scoped to.

End-to-end flow

Typical lifecycle for making a tool callable by an agent.

1) Create a tool with POST /api/ext/tool (or pick one from GET /api/ext/tool). 2) Create or choose an agent with GET /api/ext/agent. 3) Link them here — the response id is the link_id. 4) Later, detach with DELETE /api/ext/tool/unlink/{link_id}.

Response fields

Link record

id is the link_id used to unlink. tool_id and agent_id echo the linked pair, project_id is the owning project, and created_at / updated_at are the link timestamps.
