Excalidraw Architect MCP vs KiCad MCP Pro Server
A side-by-side look at the Excalidraw Architect MCP and KiCad MCP Pro Server 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 KiCad MCP Pro Server 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
KiCad MCP Pro Server tools 24
kicad_list_tool_categoriesList all available tool categories and capabilities. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.kicad_get_tools_in_categoryGet tool names in a category, optionally filtered by maturity.kicad_set_projectSet the active KiCad project directory and file paths. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.kicad_get_project_infoShow the currently configured KiCad project paths. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.project_design_workflowReturn the professional PCB design workflow as a typed phase state machine. Lays out the canonical Planner -> Builder -> Verifier -> Fixer -> Release sequence, with the high-level tool and the quality gates each phase must pass. Pass the phases already finished in ``completed_phases``; the tool marks them COMPLETE, reports the first remaining phase as READY (the current step) with its next action and gates, and flags when a human gate is required. Read-only and headless — use it to drive an autonomous design run step by step.project_get_next_actionReturn the next high-priority action derived from the current project gate.kicad_get_versionGet KiCad version information and current connection status. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.pcb_get_board_summarySummarize the current board. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.pcb_visual_qaHeadless PCB readability QA: off-board parts, silk and body overlap. A fast, file-backed first pass that runs without a live KiCad: it flags footprints whose body leaves the board outline, reference designators that collide on the silkscreen, and overlapping footprint bodies — directly from the ``.kicad_pcb`` geometry. It complements (does not replace) the authoritative DRC run, which remains the sign-off check for courtyard and silk clipping. Returns JSON with an overall PASS/INFO/WARN status and per-finding refs/positions.pcb_get_stackupShow the current stackup. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.pcb_get_design_rulesRead the active board design rules file when available. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.sch_get_symbolsList all schematic symbols, optionally from a child sheet. This KiCad MCP Pro tool supports production EDA automation workflows for MCP clients.- +12 more on the listing page

Frequently asked questions
Excalidraw Architect MCP is categorized under Architecture & Design and uses a local stdio subprocess. KiCad MCP Pro Server belongs to Architecture & Design and uses a local stdio subprocess. Pick Excalidraw Architect MCP for architecture & design work and KiCad MCP Pro Server 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. KiCad MCP Pro Server is listed as free. Auth: no auth required. 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 kicad-mcp-pro-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
