Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (94 of 95), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (94 of 95), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to growthbook/growthbook-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 565 tokens (~188/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Dependencies 94 packages
94 packages in the resolved dependency tree · 94 deprecated · 29 stale.
The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
growthbook_call_api Call GrowthBook API ~177
Make an authenticated HTTP request to the GrowthBook REST API on the user's behalf. Use method + path (+ optional JSON body) exactly as shown in skill workflows that mention gb-call. Paths typically start with /api/v1/ or /api/v2/. Returns the raw response body on success. IMPORTANT: Before POST, PUT, PATCH, or DELETE, confirm with the user (summarize method, path, and body) unless they have already explicitly instructed you to perform that mutation. GET requests do not need confirmation.
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | — | Optional JSON request body as a string (for POST/PUT/PATCH) |
| method | string | yes | HTTP method |
| path | string | yes | API path including query string if needed, e.g. /api/v1/projects or /api/v2/features/my-flag |
No output schema declared.
No examples provided.
growthbook_list_skills List GrowthBook Skills ~61
List available GrowthBook agent skills (name + description). Use growthbook_read_skill to load the full workflow for a skill before acting. Skills encode how to accomplish GrowthBook tasks well; use growthbook_call_api to execute the REST calls they describe.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
growthbook_read_skill Read GrowthBook Skill ~82
Return the full markdown content of a GrowthBook skill by name (from growthbook_list_skills). Follow the skill's workflow; when it shows `gb-call <METHOD> <PATH> [body]`, use the growthbook_call_api tool with those arguments instead.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Skill name, e.g. flag-create or experiment-launch |
No output schema declared.
No examples provided.
