## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to rodri-oliveira-dev/complexity-analyzers).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 350 tokens (~116/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.

### 2026-10-25 (score 82)

First indexed and scored.

## MCP tools (3)

### `analyze_project` (~153 tokens)

Analyzes a C# project or solution below --root. Returns a deterministic snapshot with explicit Unknown results. Use responseMode='summary' to reduce context, then query_member_evidence with analysisId for exact member details.

Input parameters:

- `maxMembers` (integer|null): Maximum member summaries (1-500) when responseMode is 'summary'; default 100. Supplying it in full mode is rejected.
- `path` (string, required): Relative or absolute path to a .csproj, .sln, or .slnx file below the configured --root.
- `responseMode` (string): Response detail: 'full' preserves the complete report; 'summary' returns a bounded member index with explicit truncation metadata.

### `query_member_evidence` (~119 tokens)

Returns one member's estimate and evidence by exact StableId. Pass analyze_project's analysisId to reuse that immutable snapshot; omit it to analyze current files again.

Input parameters:

- `analysisId` (string|null): Optional analysisId returned by analyze_project. Reuses only that exact in-memory snapshot and fails explicitly if unavailable.
- `path` (string, required): Relative or absolute path to a .csproj, .sln, or .slnx file below the configured --root.
- `stableId` (string, required): Exact StableId returned by analyze_project.

### `compare_snapshots` (~78 tokens)

Compares baseline and current complexity-snapshot JSON files below --root. Unknown estimates remain incomparable and are never promoted to proven regressions.

Input parameters:

- `baselinePath` (string, required): Relative or absolute path to the baseline .json snapshot below --root.
- `currentPath` (string, required): Relative or absolute path to the current .json snapshot below --root.

## Common questions

### What is the Complexity Analysis MCP server?

Complexity Analysis is an MCP server listed in the public MCP registry as io.github.rodri-oliveira-dev/complexity-analysis. Analyze C# complexity, inspect member evidence, and compare deterministic snapshots. This page covers its NuGet package (ComplexityAnalysis.Mcp).

### Is the Complexity Analysis MCP server safe to use?

Complexity Analysis scores 87 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Complexity Analysis MCP server expose?

Complexity Analysis exposes 3 tools: analyze_project, query_member_evidence, compare_snapshots. Their descriptions and schemas cost roughly 350 tokens of context every time the server is loaded.

### Is the Complexity Analysis MCP server still maintained?

Complexity Analysis is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Complexity Analysis MCP server under?

Complexity Analysis declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
