get_ast_context

Get the treesitter scope chain at a position (shows enclosing functions, classes, blocks)

workspace_symbols

Search workspace symbols via LSP (functions, classes, types across the project)

get_diagnostics

Get LSP diagnostics (errors, warnings) for a file or the entire workspace

get_references

Find all references to a symbol at a given position via LSP

goto_definition

Go to definition of a symbol at a given position via LSP

Tool 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

14/14 tools missing one or more hints — vim_health (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); restart_lsp (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_lsp (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 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.

Tool inputs are validated

10/14 tool handlers declare input schemas (71%)

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.).

Shell command execution

1 call in production code run through a shell (src/utils.ts:27)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
