enterprise-architect-mcp
A read-only Model Context Protocol (MCP) server for Sparx Enterprise Architect .qea exports. Gives AI agents access to EA analysis models — search elements, navigate packages, read use case scenarios, and traverse connectors — without a running EA instance.

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
11/11 tools missing one or more hints — ea_get_connectors (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ea_get_diagram_elements (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ea_list_diagrams (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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
2 tools describe read intent but their handlers mutate — ea_get_connectors (line 55: FEATURE_LINK_RE.exec(styleEx)); ea_get_diagram_elements (line 46: FEATURE_LINK_RE.exec(styleEx))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
10/11 tool handlers declare input schemas (91%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool description accuracy
ea_get_connectors: description implies read-only but handler writes/deletes/executes; ea_get_diagram_elements: 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.
