Symvanta — Claude Code MCP server: features and setup
Connect an agent to a code graph to inspect callers, dependencies, tests, and the impact of a proposed edit.
claude mcp add --transport http code-graph https://mcp.symvanta.com/mcpWhat Symvanta does
Symvanta gives an agent access to a graph built from indexed code. Ask how a behavior works, follow a function’s callers and dependencies, locate tests for a symbol, or find the handler behind an HTTP route. The codebase needs to be indexed in Symvanta for these graph lookups to work.
The Claude Code plugin adds slash commands and session-start context. Its hooks can enrich searches and file reads with graph details, and show a symbol’s blast radius before a code edit. Hook failures let the original operation continue without added context. First connection requires OAuth; a non-default server needs its full /mcp endpoint URL, with no trailing slash.
What it helps with
- trace callers and dependencies for a function
- check a symbol’s impact before editing it
- find tests that cover a symbol
- locate the handler for an HTTP route
- review recent file and commit history
Example prompts for the agent
- Trace the call chain for
parseConfigwith/symvanta:trace parseConfig. - Check the blast radius of
UserServicebefore editing it:/symvanta:blast UserService. - Find tests covering
createSessionwith/symvanta:tests createSession.

Questions about Symvanta
How do I install Symvanta in Claude Code?
Add its marketplace with /plugin marketplace add https://symvanta.com/plugin/marketplace.json, then run /plugin install symvanta@symvanta. Sign in with OAuth when the first connection prompts you.
What does Symvanta do?
It lets an agent query an indexed code graph for callers, dependencies, tests, and change impact. It also answers codebase behavior questions and maps modules.
Does Symvanta require an indexed project?
Yes. Graph lookups rely on a codebase indexed in Symvanta. Hooks stay quiet in a checkout that is not attached to a Symvanta project.
