httap
An MCP server that enables AI agents to intercept, inspect, and modify HTTP traffic, with tools for searching, filtering, and managing captured requests and interceptors.

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.
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
16/16 tools missing one or more hints — httap_get_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); httap_list_requests (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); httap_get_request (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 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.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — httap_delete_interceptor deletes at line 1247 (fsp.unlink(absolutePath))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
9/16 tool handlers declare input schemas (56%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 0/16 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
28 child_process calls — 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, 4 high severity in production deps — undici@7.21.0 (high), undici@7.21.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
2/15 production deps stale: ink-use-stdout-dimensions@2022-05-05 (4.1y), cli-highlight@2023-04-12 (3.2y)
