archmcp
archmcp is a local MCP (Model Context Protocol) server that scans repositories and produces compact architectural snapshots (modules/symbols/dependencies/routes/architectural patterns). It runs as a stdio-based MCP server and can also generate one-shot snapshots via a CLI.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Intended as a local stdio MCP server (not a network service), so transport-layer concerns are reduced, but there’s no explicit guidance on sandboxing, filesystem access limits, or whether scanned content could include secrets. The README does not describe how credentials/secrets in scanned files are handled or redacted. Build-time/security hygiene depends on Go dependencies, but no CVE posture was provided.
⚡ Reliability
Best When
You want to reduce “guessing” time for LLM-based code exploration by giving structured architectural facts up front, especially for unfamiliar or multi-language/multi-repo systems.
Avoid When
You need a production-grade, authenticated network API for end users; this tool is intended for local developer/agent workflows.
Use Cases
- • Provide upfront architecture context to an AI coding agent before it starts reading code
- • Generate cross-repo architectural context and query facts across multiple repositories (append mode)
- • Support architecture Q&A such as “what depends on what”, route discovery, and cycle/layer violation detection
Not For
- • A full documentation site or visualization dashboard
- • Replacing code search/reading/grep when implementation details are needed
- • Running as a remote hosted service (it’s designed to run locally as an MCP server)
Interface
Authentication
No authentication described in the README. As a local stdio MCP server, access is constrained to the local MCP client connection model.
Pricing
No pricing information provided; repository appears to be open-source (MIT) and local-run.
Agent Metadata
Known Gotchas
- ⚠ May ignore certain files by default (e.g., tests and docs, plus YAML/JSON configs). If relevant code/config is excluded, the snapshot may be incomplete.
- ⚠ Artifacts and caches are written to .archmcp by default; ensure paths and ignore rules match your workflow.
- ⚠ When doing multi-repo append mode, ensure you use consistent repo labeling and filters so queries target the right subset.
