Anvien Guide
Quick reference for all Anvien MCP tools, resources, and the knowledge graph schema.
Always Start Here
For any task involving code understanding, debugging, impact analysis, or refactoring:
- Read
anvien://repo/{name}/context — codebase overview + check index freshness
- Match your task to a skill below and read that skill file
- Follow the skill's workflow and checklist
If step 1 warns the index is stale, run anvien analyze in the terminal first.

Tools Reference
| Tool |
What it gives you |
query |
Process-grouped code intelligence — execution flows related to a concept |
context |
360-degree symbol view — categorized refs, processes it participates in |
impact |
Symbol blast radius — what breaks at depth 1/2/3 with confidence |
detect_changes |
Git-diff impact — what do your current changes affect |
rename |
Multi-file coordinated rename with confidence-tagged edits |
cypher |
Raw graph queries (read anvien://repo/{name}/schema first) |
list_repos |
Discover indexed repos |
Resources Reference
Lightweight reads (~100-500 tokens) for navigation:
| Resource |
Content |
anvien://repo/{name}/context |
Stats, staleness check |
anvien://repo/{name}/clusters |
All functional areas with cohesion scores |
anvien://repo/{name}/cluster/{clusterName} |
Area members |
anvien://repo/{name}/processes |
All execution flows |
anvien://repo/{name}/process/{processName} |
Step-by-step trace |
anvien://repo/{name}/schema |
Graph schema for Cypher |
Graph Schema
Nodes: File, Function, Class, Interface, Method, Community, Process
Edges (via CodeRelation.type): CALLS, IMPORTS, EXTENDS, IMPLEMENTS, DEFINES, MEMBER_OF, STEP_IN_PROCESS
MATCH (caller)-[:CodeRelation {type: 'CALLS'}]->(f:Function {name: "myFunc"})
RETURN caller.name, caller.filePath
