// blast radius
Exact totals, explicit gaps
Graph search returns exact caller totals across the monorepo and says whether the list is complete. Calls matched by name only are listed separately.
self-serve, free tier
The edit is easy. Knowing what breaks is hard.
Before a refactor, your agent should know every caller, importer, and dependent. Maguyva answers that from the real call graph, not a grep.
Impact analysis lists everything that depends on the code you're about to change. Maguyva returns those callers and dependents with file paths and line numbers, across packages and languages, before the agent edits a line.
free plan: 3 repos, 50K indexed lines, no card.
// before you ship
Grounded in real lines
File paths and line numbers, so the migration list is right before CI goes red.
// any client
23 documented MCP clients
One remote MCP integration. No local indexer, no IDE to switch.
Check blast radius before you refactor.
Index one repo you already know and ask what calls the function you are about to change.

Index a repo you know
Pick the codebase where a refactor scares you. Free tier: 3 repos, 50K indexed lines.

Ask what breaks if you change it
Get callers and importers from the real graph, not a grep, with exact totals and a completeness flag, before you touch a line.
