## What it 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.

## Requirements
- Remote server: `https://mcp.symvanta.com/mcp`

## Install

### Claude Code (native platform)

**Platform CLI: remote server**
```bash
claude mcp add --transport http code-graph https://mcp.symvanta.com/mcp
```

### Codex

**Platform CLI: remote server**
```bash
codex mcp add symvanta --url https://mcp.symvanta.com/mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "symvanta": {
            "url": "https://mcp.symvanta.com/mcp"
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "symvanta": {
            "type": "http",
            "url": "https://mcp.symvanta.com/mcp"
        }
    }
}
```

### Gemini CLI

**Platform CLI: remote server**
```bash
gemini mcp add -t http symvanta https://mcp.symvanta.com/mcp
```

## When to use it
- 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
- Trace the call chain for `parseConfig` with `/symvanta:trace parseConfig`.
- Check the blast radius of `UserService` before editing it: `/symvanta:blast UserService`.
- Find tests covering `createSession` with `/symvanta:tests createSession`.
