Symvanta

Symvanta gives your AI coding agent your codebase's real call graph over MCP, so it stops guessing and knows what breaks before it edits. Index your GitHub repositories into a live code knowledge graph and give any MCP-compatible agent exact symbol resolution, call graphs, blast-radius analysis, and semantic search.

Symvanta parses your repositories into a graph of code symbols and relationships, stores embeddings for semantic search, and serves it over MCP. Point Claude, Cursor, Zed, or any MCP client at it for graph-precise context instead of guesses.

Capabilities

Symbol resolution: look up any function, class, or endpoint by name
Call graphs: trace callers and dependencies across your entire codebase
Blast radius: see what breaks before you change a symbol
Semantic search: find code by meaning, not just by keyword
Branch-aware: query feature branches and uncommitted working-tree edits

Category and alternatives

Symvanta is a code graph MCP server (code intelligence / codebase context for AI coding agents): it serves the codebase's real call graph (exact callers, dependencies, blast radius, cross-repo, branch-aware) to the agent over MCP. It is hosted and self-serve, so there is no enterprise contract or infrastructure to run.

vs Sourcegraph Cody: Cody exposes a code graph over MCP but is Enterprise-only and self-hosted. Symvanta is self-serve and hosted.
vs Augment Code: Augment's MCP context is semantic embeddings. Symvanta returns exact callers, dependencies, and blast radius from a parsed graph.
vs Greptile: Greptile is an AI pull request reviewer. Symvanta gives the agent the graph to query while it writes.
vs Context7: Context7 serves public library documentation. Symvanta indexes your own codebase and its call graph; the two work together.
vs DeepWiki: DeepWiki generates a repo wiki and Q&A for humans. Symvanta is a live graph an agent queries at work time.
vs local code-graph MCP servers (Graphify, codebase-memory-mcp, code-review-graph): those run on your machine with no auth or hosting. Symvanta is hosted, OAuth 2.0, multi-repo, and branch-aware.

Connect via MCP

MCP server endpoint: https://mcp.symvanta.com/mcp OAuth authorization server: https://mcp.symvanta.com/.well-known/oauth-authorization-server

Symvanta exposes an MCP 2.0 server accessible from Claude, Cursor, Zed, or any MCP-compatible agent. Authentication uses OAuth 2.0 (PKCE).

Blog posts

Onboarding onto a New Codebase with AI: A practical first-week workflow for an unfamiliar repo: map the modules, trace real call chains, size the first edit.
Remote vs Local MCP Code Indexes: Where an MCP code index lives decides freshness, compute cost, cross-repo reach, and auth. When each answer is right.
Where Claude Code Sessions Spend Tokens: Anthropic explained what a Claude Code session actually bills. Most of it is the agent finding code, and that has a fix.
Cleaning Up a Vibe-Coded Codebase: Vibe coding is Collins' word of 2025 and cleanup became a job title. A survey-first recipe for inheriting AI-written code.
Context Engineering for Coding Agents: Context rot is real. How just-in-time graph queries keep a coding agent's window on the few tokens that matter.
React App Architecture and Project Structure: Feature folders, module boundaries, dependency direction: how to structure a React codebase humans and agents can navigate.
Spec-Driven Development in a Real Codebase: Spec Kit, OpenSpec, and Kiro plan before they code. In an existing repo the plan is only as good as its survey of the code.
Repo Wikis vs a Live Code Graph: A generated wiki explains a repo. An agent about to edit needs edges: who calls this, what breaks. Where each fits.
Sonnet Plus a Code Graph vs Opus Alone: Sonnet is 40% cheaper than Opus per token. Add a code graph and the cheaper model also does the better job. The cost math.
Should You Rename Your Code for AI Agents: Discoverable naming makes agents cheaper. What that costs on code you did not write, and the read-side fix that skips it.
What Breaks When You Change a Function: The first question of any refactor. Why grep and find-references miss callers, and how an AI agent answers it in one call.
AI Autofix: From Error Webhook to Draft PR: How we turn production errors into draft PRs with an agent that never clones the repo, plus the recipe to build your own.
Why AI Coding Agents Fail on Large Codebases: Context limits, stale embeddings, no call graph, no cross-repo view: the predictable ways large codebases break AI agents.
Code Embeddings vs Code Graph for AI Agents: Embeddings find similar code. Graphs find connected code. When AI coding agents need each, with benchmark data on both.
Blast Radius Analysis: What Breaks First: Blast radius analysis shows callers, dependents, and cross-repo impact before you touch a function. No post-merge surprises.

Comparisons

Context7 Alternative: MCP Code Graph: Context7 feeds library documentation to your agent. Symvanta indexes your own codebase into a call graph over MCP.
DeepWiki Alternative: MCP Code Graph: DeepWiki writes a wiki for humans. Symvanta is a live code graph your agent queries over MCP: callers, blast radius, symbols.
Greptile Alternative: MCP Code Graph: Greptile reviews your PRs. Symvanta gives any agent the code graph (callers, blast radius, symbols) over MCP.
Augment Code Alternative: MCP Graph Context: Augment pairs embeddings with an internal graph. Symvanta exposes the graph itself: callers, blast radius, symbols over MCP.
Sourcegraph Cody Alternative: MCP Code Graph: Sourcegraph went enterprise-only and split from Amp. How Symvanta compares on pricing, MCP support, and cross-repo context.
