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 → Why this is hard to score →
Supply Chain Security73
- No malware found by supply-chain analysis.Pass
- CVE check failed: an unpatched critical CVE affects this package; the score is capped at 0. See how to fix → View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 32 of 100 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 193 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability82
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 358 tokens (~89/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "check_merge_safety" implies "merge" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_branches ~91
Deep semantic analysis between two branches. Returns a detailed per-file report of all semantic changes and conflicts, including cross-file dependency issues.
| Name | Type | Req | Description |
|---|---|---|---|
| baseBranch | string | – | Common base branch (auto-detected if not provided) |
| branchA | string | yes | First branch to compare |
| branchB | string | yes | Second branch to compare |
| repoPath | string | yes | Absolute path to the Git repository |
No output schema declared.
No examples provided.
analyze_file_pair ~82
Deep-dive semantic diff of a single file between two branches. Shows exactly what each branch changed and where conflicts arise.
| Name | Type | Req | Description |
|---|---|---|---|
| branchA | string | yes | First branch |
| branchB | string | yes | Second branch |
| filePath | string | yes | Path to the file within the repository |
| repoPath | string | yes | Absolute path to the Git repository |
No output schema declared.
No examples provided.
check_merge_safety ~96
Quick pre-merge safety check. Analyzes two branches for semantic conflicts that Git would miss (signature changes, removed exports, parameter mismatches, etc.). Returns a risk score: safe/warning/danger.
| Name | Type | Req | Description |
|---|---|---|---|
| repoPath | string | yes | Absolute path to the Git repository |
| sourceBranch | string | yes | The branch being merged (source) |

Lists all semantic changes on a branch (function additions/removals, export changes, type changes, etc.) relative to a base. Useful for understanding what semantically changed.
| Name | Type | Req | Description |
|---|---|---|---|
| baseBranch | string | – | Base branch to compare against (defaults to merge-base with HEAD) |
| branch | string | yes | Branch to analyze |
| repoPath | string | yes | Absolute path to the Git repository |
No output schema declared.
No examples provided.
