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.
search_cabsSearch for active, currently available cabs in a city. Use this before booking when the rider asks for availability, asks to find a cab, or gives a trip request such as "get me a sedan from Gachibowli to the airport around 6pm". Return results include cab id, driver, vehicle type, plate number, an…
get_fare_estimateCalculate a fare estimate without creating a booking. Use this when the rider asks what a trip will cost. This tool applies distance, duration, city fare overrides, vehicle type pricing, and surge pricing for the requested time. This tool does not reserve a cab and does not write a booking. It ret…
book_rideCreate a confirmed ride booking for a specific cab id. Use only after the rider has chosen a cab or clearly asks to book a specific cab from search results. Do not use this for browsing availability or estimating prices. The server recalculates the fare from database pricing, route distance, and s…
cancel_rideCancel an existing booking. Use only when the rider explicitly asks to cancel a booking. The tool rejects already-completed and already-cancelled rides.
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
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
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
4/4 tools missing one or more hints — search_cabs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_fare_estimate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); book_ride (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 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
Only 0/4 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/4 tool handlers wrap calls in try/catch (0%)
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.).
Tool test coverage
Only 0/4 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
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.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.5 (high), @modelcontextprotocol/sdk@1.17.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
