Roam-Code
Local structural analysis engine for software codebases that builds a semantic SQLite graph enabling AI coding agents to perform instant architectural queries, impact analysis, anti-pattern detection, and multi-agent coordination across 27 programming languages via 102 MCP tools.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Roam Research graph MCP. API key or graph token required. Personal knowledge graph — treat as sensitive personal data. Local or self-hosted deployment preferred.
⚡ Reliability
Best When
You have AI coding agents working on medium-to-large codebases and need them to reason about architecture, dependencies, and change impact without expensive repeated file reads.
Avoid When
Your codebase is small and well-understood, or you only need bug detection (SAST) rather than architectural intelligence.
Use Cases
- • Pre-change blast radius analysis so agents know which files will be affected before editing
- • Multi-agent parallel work coordination with conflict-free partitioning of codebase regions
- • Architecture health monitoring and technical debt prioritization in CI/CD pipelines
- • Security vulnerability reachability mapping from entry points through call graphs
- • Refactoring planning with simulation of outcome before applying changes
Not For
- • Real-time code execution or runtime profiling
- • Single-file or trivially small codebases where graph analysis adds no value
- • Teams already satisfied with SonarQube/CodeScene for SAST without needing architecture-level analysis
Interface
Authentication
Fully local execution with no API keys, no external dependencies, and no telemetry. Works in air-gapped environments. No authentication needed.
Pricing
MIT license. Fully local; zero runtime costs beyond compute for initial index build.
Agent Metadata
Known Gotchas
- ⚠ Initial index build time scales with codebase size — large repos may take minutes before agents can query
- ⚠ Index must be rebuilt or incrementally updated when files change — stale index produces incorrect blast radius analysis
- ⚠ 102 MCP tools is a very large tool surface; agents without good tool selection may have high tool-choice overhead
- ⚠ fastmcp optional dependency is required for the MCP server mode — not installed by default with pip install roam-code
- ⚠ Tier 1 language support is comprehensive but Tier 2 (generic tree-sitter) may produce lower-quality graphs for some languages
