Lumerical MCP Server
Enables natural-language-driven automation of Ansys Lumerical photonic simulations (FDTD, MODE, DEVICE, INTERCONNECT) with 40+ tools for geometry, materials, sources, monitors, solvers, results, optimization, and documentation.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

LUMERICAL_HOMETool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
87/87 tools missing one or more hints — lumerical_ai_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lumerical_ai_chat (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lumerical_ai_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +84 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
18 tools describe read intent but their handlers mutate — lumerical_ai_status (line 136: result = subprocess.run(); lumerical_ai_search (line 265: result = subprocess.run(); lumerical_cml_status (line 116: result = subprocess.run()
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool description accuracy
17 tools have description/behavior mismatches: lumerical_ai_status: description implies read-only but handler writes/deletes/executes; lumerical_ai_search: description implies read-only but handler writes/deletes/executes; lumerical_cml_status: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
