About Eraser MCP

Eraser MCP lets agents generate, create, read, search, update, export, and organize technical diagrams and documents in an Eraser workspace.

What an agent can do in Eraser MCP

Every Eraser MCP action is classed by the platform as a read, a change or a send. Reads run at once. Changes and sends are held for a person by default.

Runs at once (reads)

Looks things up in Eraser MCP without asking first. 16 actions.

  • Export diagramRender a canvas diagram to PNG or JPEG and return a temporary image URL. Tell the user to download it from the returned imageUrl. Set format: "drawio" instead to export an editable draw.io (diagrams.n
  • Export documentExport a file's markdown document body as a downloadable artifact.
  • Export fileReturns the Eraser file URL for PDF export. NOTE: programmatic PDF export is not yet available via MCP — this returns a link for the user to export from the Eraser app's export menu, not a downloadabl
  • Get diagramFetch a diagram's metadata and DSL/JSON code. For freeform diagrams, set includeFreeformDefinition: true to get the full scene structure (elements, connections, titles). Need a PNG image of the diagra
  • Get documentFetch the full markdown body of a file's document.
  • Get fileFetch a file's metadata, document outline (headers), and the list of diagrams in it.
  • Get folderFetch a folder by id.
  • Get meFetch the current user, active team, and team memberships.
  • Get presetFetch a preset including its rules, templates, and references.
  • Get template or referenceFetch a template/reference's metadata, document outline, and diagram list.
  • List diagramsList the diagrams contained in a file.
  • List filesList files in the team workspace, optionally scoped to a folder.

  • List foldersList folders. Pass `parentFolderId` to scope to direct children of a folder (or `null` for top-level only). Pass `nameContains` to resolve a folder the user names by string (e.g. 'the Engineering fold
  • List presetsList the team's presets. Pass `nameContains` to resolve a preset the user names by string (e.g. 'the Marketing preset') without scanning the full list — much cheaper in context tokens.
  • List teamsList the teams the current user belongs to (OAuth only).
  • SearchFull-text and semantic search across files or diagrams. Omit 'kind' for content search (finds matching blocks). Use kind: 'file' only to look up a file by name (no block content returned). Use kind: '

Held for approval by default (changes and sends)

  • Create folderCreate a new folder.
  • Create presetCreate a new preset (the team-level container for AI styling: templates, references, and rules). After creating, the typical next steps to make the preset useful are: 1. Add example files as templates
