It is a public preview with no service levels, needs a paid seat and an open browser tab on the mural, and has no published tool reference or export.\n\n**PlantUML.** One Java command reads diagram text from stdin and writes PNG, SVG, PDF or ASCII with no account, and CI passed on the last eight pushes. The default security profile lets diagram text read any local file and fetch any URL, and the documentation still lists chronology diagrams that release 1.2026.2 switched off.\n\n## Before you call either\n\n### Mural MCP\n\n1. Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool\n2. Work on one mural at a time and name it explicitly when switching\n3. Request only murals:read when the task only reads a board\n4. Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals\n5. If a tool is missing or renamed, reconnect the connector to refresh the cached tool list\n\n### PlantUML\n\n1. Set `PLANTUML_SECURITY_PROFILE` to `SANDBOX` or `ALLOWLIST` before rendering text from an untrusted source. The default profile lets `!include` read local files and fetch URLs\n2. Run `java -jar plantuml.jar --check-syntax` with `-stdrpt` first and read the exit status. Without `--no-error-image` a syntax error still writes an image of the error text\n3. Pass `-pipe` with `--svg`, `--txt` or `--utxt` to work without files. `--txt` output suits a text-only model\n4. Start the local server as `-picoweb:8080:127.0.0.1`. Without the bind address it listens on every interface\n5. Use `npx -y @plantuml/mcp-js` when no Java runtime is present. It renders SVG only, so use the jar for PNG or PDF\n\n## Questions\n\n### Which is better for AI agents, Mural MCP or PlantUML?\n\nPlantUML scores 66.9 (B) on agent readiness against Mural MCP's 41.9 (E), and leads in 5 of 7 scored categories. Mural MCP leads on security \u0026 auth.\n\n### Can an agent call Mural MCP and PlantUML without installing anything?\n\nMural MCP has a hosted endpoint at https://mcp-canvas.mural.co/mcp. No hosted endpoint is listed for PlantUML.\n\n### Are Mural MCP and PlantUML open source?\n\nNo open-source release is listed for Mural MCP. PlantUML is open source (GPL-3.0-or-later).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mural-mcp-vs-plantuml.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mural-mcp-vs-plantuml.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mural-mcp\", \"b\": \"plantuml\"}`.
