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.
axios Vulnerable to Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`
Allocation of Resources Without Limits or Throttling in Axios
Axios Node HTTP adapter can use an inherited proxy after interceptor config cloning
Axios: Regular Expression Denial of Service (ReDoS) via Cookie Name Injection
Axios: Proxy-Authorization header leaks to redirect target when proxy is re-evaluated to direct connection
META_ACCESS_TOKENLong-lived Meta Graph API token for Facebook Pages, Instagram, Ads Manager, Commerce, Conversions API, Audiences, Insights, and utility tools.THREADS_ACCESS_TOKENThreads API token. Required only for Threads publishing, replies, and insights tools.openWorldHint matches behaviour
143 tools claim openWorldHint=false but make outbound HTTP — meta_search_ad_library → /ads_archive (line 81); meta_list_campaigns → dynamic (line 101); meta_get_campaign → dynamic (line 161)
Either flip openWorldHint to true (acknowledging external reach) or refactor the handler to avoid outbound HTTP. If the only network calls are to a known fixed endpoint that you consider part of the tool itself, document that and keep openWorldHint=false; otherwise true is honest.
Tool test coverage
Only 10/200 tools referenced in tests (5%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 7 high severity in production deps — axios@1.15.2 (high), axios@1.15.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
