Symvanta MCP
Code Graph MCP Server for AI Coding Agents
A coding agent can read files and run grep, but those tools do not tell it which symbol a name refers to, who calls that symbol across repositories, or what a proposed edit can break. Symvanta parses your GitHub repositories into a live code graph and serves that graph through a hosted MCP endpoint.
Add the endpoint once. Your agent can then resolve symbols, trace callers and dependencies, search by meaning, and check blast radius before it edits.

The first connection opens an OAuth sign-in. You do not need to generate or paste a key.
What a code graph MCP server provides
A file server returns source text. A semantic index returns similar snippets. A code graph returns relationships between specific symbols.
Symvanta exposes the relationships an agent needs while it plans and edits:
- Resolve a function, class, method, or endpoint by identity.
- Find direct and transitive callers across indexed repositories.
- Trace the dependencies a symbol uses.
- Estimate the blast radius of a proposed change.
- Search code by meaning when the exact symbol name is unknown.
- Query tracked feature branches and working-tree overlays.
The agent receives focused results with source locations. It reads the relevant code after it knows which files matter.
Code graph, semantic search, and grep
These retrieval methods answer different questions.
| Method | Best question | Main limitation |
|---|---|---|
| Grep | Where does this exact text appear? | Names do not prove symbol identity or dependency direction. |
| Semantic search | Which code is related to this concept? | Similarity does not prove that one symbol calls another. |
| Code graph | Who calls this symbol, what does it depend on, and what can this change affect? | Static relationships cannot observe every runtime-only behavior. |
Symvanta combines semantic search with parsed graph relationships. Your agent can discover a concept, resolve the exact symbol, and then inspect its callers and impact. If you are choosing where that graph should run, the code graph MCP server comparison covers hosted, instance-backed, and local options.
Cross-repository and branch-aware context
Production changes often cross repository boundaries. A frontend calls an API in another repository. A shared package has consumers in several services. A feature branch changes a contract before the default branch does.
Symvanta keeps those relationships in one graph. An MCP client can query the active indexed revision, pin a tracked branch, or index a working-tree overlay for the current session. This gives the agent context for the code you are changing, not only the last default-branch snapshot.
Works with the agent you already use
The hosted endpoint works with MCP-compatible clients, including:
- Claude Code and Claude Desktop
- Cursor
- Codex CLI
- Amp
- VS Code and GitHub Copilot agent mode
- Windsurf
- Cline and Roo Code
- JetBrains tools
- Zed and Gemini CLI
See the integration guides for client-specific setup.
Hosted authentication and team access
Symvanta uses OAuth 2.0 with PKCE for interactive clients. CI runners and cloud agents that cannot complete an interactive login can use a scoped API credential.
Your team shares one continuously updated graph. Each developer does not need to build and maintain a separate local index.
Check impact before the agent edits
The highest-value graph query happens before a change. Ask which callers, routes, tests, and repositories depend on a symbol before the agent modifies it.

Start with your own repository
Every plan includes a 7-day trial with no credit card. Connect GitHub, index a repository, and add the MCP endpoint to your coding agent.
