Excalidraw Architect MCP vs Mimic AI
A side-by-side look at the Excalidraw Architect MCP and Mimic AI MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Excalidraw Architect MCP for architecture & design work as a local process; choose Mimic AI for architecture & design as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Excalidraw Architect MCP tools 26
create_diagramCreate a new Excalidraw diagram of any supported type. Two input modes: 1. **Graph types** (``architecture``, ``flowchart``) - pass ``nodes`` and ``connections``. The tool handles layout, styling, and rendering; no coordinates needed. 2. **Typed diagrams** (every other type) - pass ``diagram_type`` and a ``spec`` object shaped for that type. Call ``list_diagram_types`` to choose a type and ``get_diagram_schema`` to see its spec shape.mermaid_to_excalidrawConvert Mermaid flowchart syntax into an Excalidraw diagram. Supports the mermaid flowchart subset that AI agents commonly generate: - Directions: graph TD, LR, BT, RL - Node shapes: [text], {text}, ((text)), ([text]) - Edge types: -->, ---, -.-> ==> with |label| - Subgraphs: subgraph Title ... end Component types are auto-detected from node labels (e.g., a node labeled "PostgreSQL DB" automatically gets database styling).modify_diagramModify an existing Excalidraw diagram created by this tool. Supports iterative editing: add components, remove nodes, update labels, and rewire connections - without recreating the entire diagram. IMPORTANT: Call get_diagram_info first to understand the current diagram state before making modifications. For **typed diagrams** (sequence, pyramid, bar, swimlane, ...) there is a single operation: {"op": "update_spec", "patch": {"tiers": [...], "title": "New title"}} The patch is deep-merged into the stored spec and the diagram re-rendered. Lists are replaced wholesale, so send the complete list to change one entry. The node/connection operations below apply to architecture and flowchart diagrams only.get_diagram_infoGet a structured summary of an existing Excalidraw diagram. Call this BEFORE modify_diagram to understand what nodes and connections currently exist. The summary includes node ids, labels, component types, and the full connection topology.export_diagramExport an .excalidraw file to SVG or PNG image. Converts an existing .excalidraw diagram into a portable image file without requiring a browser or the Excalidraw application.list_diagram_typesList every supported diagram type with guidance on when to use it. Call this BEFORE create_diagram when the right diagram type isn't obvious. Picking the wrong type is the most common way a diagram fails - a swimlane drawn as a flowchart loses the handoffs that were the point. Two rules worth applying whatever you pick: - Target density ~4/10. Above 9 nodes it is probably two diagrams. - Mark only 1-2 elements "focal": true. The accent color is a signal, and using it everywhere destroys it. Returns: A table of type -> family, when to use it, and when not to.get_diagram_schemaGet the JSON schema and selection guidance for one diagram type. Call this before passing a `spec` to create_diagram for a type you have not used yet, so the payload matches on the first attempt.kg_initCreate a new architecture knowledge graph file (markdown). The knowledge graph is the persistent source of truth for your system's services and dependencies. Diagrams are rendered *from* it.kg_add_serviceAdd or update a service in the knowledge graph.kg_remove_serviceRemove a service and all dependencies touching it.kg_linkAdd a directed dependency: ``from_id`` depends on / calls ``to_id``. Both services must already exist (add them with kg_add_service first). ``style`` is one of solid/dashed/dotted/thick.kg_unlinkRemove the dependency ``from_id`` -> ``to_id``.- +14 more on the listing page
Mimic AI tools 60
mimic_statusReturns plugin connection status, current build phase, enforcement profile, knowledge store summary, and a contextual hint for what to do next.mimic_discover_dsComplete DS discovery in two steps. Step 1: call with fileKey — discovers variables, text styles, components via plugin API, caches everything, stays at Phase 1. Step 2: call again with communitySearchResults (library names from Figma MCP search_design_system) — verifies no community libraries were missed, then advances to Phase 2 (build-ready). Build tools are BLOCKED until Step 2 completes. If a community library's variables are not discoverable via the plugin API (communityVariablesRequired response), fetch them via Figma MCP search_design_system and pass as externalVariables.figma_preload_stylesSends text style keys to the plugin for caching. Call during DS setup phase.figma_preload_variablesStores DS variables in the local cache for enforcement and resolution.figma_set_session_defaultsComputes the enforcement profile from cached DS data and sends it to the plugin. Advances to Phase 2 (inventory ready).figma_list_text_stylesReturns all cached text styles from the DS.figma_preload_fill_stylesPreloads fill (color) styles into the DS cache from a library file key. Call when discovery missed fill styles (e.g. library variables not enumerable but fill styles exist in the REST API).figma_list_fill_stylesReturns all cached fill (color) styles from the DS. Use the style key as fillStyleId in create_frame, create_text, create_rectangle, create_ellipse, or set_node_fill.figma_discover_library_stylesDiscovers and caches text styles from a Figma library file.figma_discover_library_variablesDiscovers and caches variables from a Figma library file.figma_discover_library_componentsScans existing component instances on the current page to discover available DS library components, their keys, and variant properties. Call during DS discovery phase.mimic_map_componentsMaps HTML element types to DS component keys. Call once to get initial mapping. If FIGMA_TOKEN is configured (REST API discovery), all library components are already cached — missing types after the first call are confirmed gaps, proceed to build. If REST API is not available (no token), search the library via Figma MCP search_design_system for missing types, then call AGAIN with librarySearchResults to confirm gaps.- +48 more on the listing page

Frequently asked questions
Excalidraw Architect MCP is categorized under Architecture & Design and uses a local stdio subprocess. Mimic AI belongs to Architecture & Design and uses a local stdio subprocess. Pick Excalidraw Architect MCP for architecture & design work and Mimic AI for architecture & design.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Excalidraw Architect MCP is listed as free. Auth: no auth required. Mimic AI has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add bv-venky-excalidraw-architect-mcp and mimic-ai as separate keys in the same mcpServers object, and your assistant will call tools from either one.
