Tools are grouped below by category. ## Guide | Tool | Purpose | | ----------- | ----------------------------------------------------------------------------------- | | `get_guide` | **Mandatory first call.** Returns the agent's working context for the current task. | | `get_docs` | Fetch Melius documentation pages by topic. | ## Teams & Projects | Tool | Purpose | | ---------------- | ------------------------------------------ | | `team_list` | List teams your API key has access to. | | `project_list` | List projects in a team. | | `project_get` | Get a project by ID. | | `project_create` | Create a new project with an empty canvas. | ## Canvas | Tool | Purpose | | -------------------- | --------------------------------------------------------------------------------------------------------- | | `canvas_list` | List canvases in a project. | | `canvas_get` | Get canvas metadata. | | `canvas_content` | Get all nodes and edges on a canvas. | | `canvas_create` | Create a new canvas. | | `canvas_delete` | Delete a canvas and everything on it. | | `canvas_plan_layout` | Compute positions for new nodes that don't overlap existing content. **Call before `bulk_create_nodes`.** | ## Nodes | Tool | Purpose | | ------------------- | ----------------------------------------------------------------- | | `node_create` | Create a node (text, image, video, file, custom\_text, or group). | | `node_update` | Update a node's prompt, model, or settings. | | `node_set_text` | Set the literal text content of a `custom_text` node. | | `node_set_version` | Select a specific generation version on a node. | | `node_delete` | Delete a node. | | `bulk_delete_node` | Delete multiple nodes in one batch. Requires user confirmation. | | `bulk_create_nodes` | Create multiple nodes — and optionally edges — in one call. | ## Groups | Tool | Purpose | | -------------- | ------------------------------------------ | | `node_group` | Group a set of nodes into a container. | | `node_ungroup` | Dissolve a group and release its children. | ## Edges | Tool | Purpose | | ------------------- | ---------------------------------- | | `edge_create` | Connect two nodes with an edge. | | `bulk_create_edges` | Create multiple edges in one call. | | `edge_delete` | Remove an edge. | ## Runs | Tool | Purpose | | ---------------- | ------------------------------------------------------- | | `run_start` | Start an AI generation on a single node. | | `run_get` | Get the status and result of a run. | | `run_wait` | Wait for a single run to finish, fail, or be cancelled. | | `run_latest` | Get the most recent run for every node on a canvas. | | `bulk_run_start` | Start runs on multiple nodes at once. | | `bulk_run_get` | Get the status of a bulk run. | | `bulk_run_wait` | Wait for a bulk run to finish. | ## Downloads | Tool | Purpose | | ------------------- | ---------------------------------------------- | | `run_download` | Download outputs from a single run. | | `bulk_run_download` | Download outputs from a bulk run. | | `creative_download` | Download all creatives from a canvas as a ZIP. | ## Models | Tool | Purpose | | ---------------- | ----------------------------------------------------------- | | `model_list` | List available AI models, variants, and supported settings. | | `model_defaults` | See which models are used when none is specified. | ## Audio | Tool | Purpose | | ------------------- | -------------------------------------------------------------------------------- | | `audio_voice_list` | List stock ElevenLabs voices for audio nodes (text-to-speech or audio-to-audio). | | `custom_voice_list` | List the team's saved custom voices (cloned, designed, or imported). | ## Comments | Tool | Purpose | | ----------------- | ---------------------------------------------------- | | `comment_list` | List comments on a canvas. | | `comment_create` | Create a comment thread at a position on the canvas. | | `comment_reply` | Reply to an existing comment. | | `comment_resolve` | Mark a comment as resolved. | ## Presence | Tool | Purpose | | ------------------ | ------------------------------------------------------------------------ | | `show_presence` | Claim a region of the canvas. **Required before node-scoped mutations.** | | `release_presence` | Release the current presence claim. | ## Presets | Tool | Purpose | | -------------- | --------------------------------------------------------------------------------------------- | | `preset_list` | List available canvas presets — pre-built node + edge templates for common workflows. | | `preset_apply` | Apply a preset to a canvas in one call.
