The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
terminal-writeWrites input to a terminal session. To press Enter, include a real newline character in the data value (not a literal backslash-n). Real newlines are converted to \r (carriage return) for PTY compatibility. Omit data to poll for new output (returns buffered output). Use terminal-read to see full ter…
terminal-readReturns recent terminal output (ANSI-stripped). Use this to read what's on screen.
terminal-createCreates one or more terminal tabs/sessions. Use this instead of terminal-show when the terminal UI is already open. New sessions appear as tabs automatically. Defaults to one bash tab if tabs is omitted.
terminal-listLists all active terminal sessions with their IDs, labels, and titles.
terminal-customizeCustomize a terminal tab's appearance. All fields are optional — only provided fields are updated.
terminal-refreshTriggers a redraw of the running program by sending SIGWINCH (resize signal) to the PTY.
terminal-resizeResizes the PTY to match the UI terminal dimensions.
terminal-closeCloses a terminal session and kills the PTY process.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
vite: `server.fs.deny` bypass on Windows alternate paths
Vite Vulnerable to Arbitrary File Read via Vite Dev Server WebSocket
Vite has an `server.fs.deny` bypass with an invalid `request-target`
INPUTSHELLPORTTool 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
8/8 tools missing one or more hints — terminal-write (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); terminal-read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); terminal-create (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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
7/8 tool handlers declare input schemas (88%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 3/8 tool handlers wrap calls in try/catch (38%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.24.0 (high), @modelcontextprotocol/sdk@1.24.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
terminal-create: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
