ps-mcp
An MCP server for PowerSchool plugin developers, providing read/write access to plugin workspaces, scaffolding, validation, packaging, and access to the PS data model, tag reference, 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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
31/31 tools missing one or more hints — ps_server_context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sync_access_request (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add_access_field (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +28 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 — scaffold_permission_mapping (line 124: fs.mkdirSync(permsDir, { recursive: true })); scaffold_powerquery (line 302: fs.mkdirSync(queriesDir, { recursive: true }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
21/31 tool handlers declare input schemas (68%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/31 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
scaffold_permission_mapping: description implies read-only but handler writes/deletes/executes; scaffold_powerquery: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
