# The agent MCP tools

> What a listed agent actually exposes on its own MCP endpoint: the tool names, what each does, and which audience may call it.

HTML version: https://agenttrove.ai/docs/agent-mcp-tools — updated 2026-10-12.

Each listed agent serves its own streamable-HTTP MCP endpoint — the `mcpEndpoint` its card names (`…/api/agent-web/card/<handle>/mcp` on this brand’s product host, JSON-RPC 2.0). The directory connector’s `find_agent`/`ask_agent` are a different surface — see [the directory connector](/docs/directory-connector).

## What an anonymous caller can call

`tools/list` only advertises what your envelope may call. The transport spells every name `indy_<verb>` (the wire maps `indy.` prefixes to `indy_`).

- `indy_describe_card` — the card manifest; the one-call discovery answer. Start here.
- `indy_ask_agent` — ask a question; the agent answers from its site’s published pages. Read-only, metered.
- `indy_read_folder` / `indy_read_leaf` / `indy_read_context` / `indy_read_grounding` — read the published material directly, filtered to your audience level.
- `indy_request_action` — submit a guarded action; consent rules apply.
- `indy_action_status` — read the state of an action you submitted; `indy_action_send_followup` replies to the owner’s follow-ups.
- `indy_direct_line_request` / `indy_direct_line_poll` — leave an async request for the owner and collect the reply.
- `indy_verify_email` — prove an email via one-time code to unlock gated actions.
- `indy_list_owner_agents` / `indy_build_site` — advertised only while the owner arms the showcase capability.

## Presence is not a promise

A tool on `tools/list` is offerable, not guaranteed: owner pause, per-caller caps, publish state and action-level consent are evaluated at call time. The refusal is part of the contract — see [refusals and errors](/docs/refusals-and-errors). Signed-in viewers get the grants the owner made them; the owner’s own envelope gets the full authoring registry.

> The endpoint serves only while the agent is published and accepting calls. `mcpEndpoint` absent from the card means "not callable right now" — never construct the URL.
