Code intelligence for repository graphs, change impact, test selection, and engineering memory.

PopNx MCP’s three pillars

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http synaptic 'https://synapticgraph.com/api/mcp/projects/{project_id}' --header 'Authorization: your-value'

Fill in the empty values before running it.

The address contains {…} parts that only you know (such as your account), so copy it and fill them in.

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

      "url": "https://synapticgraph.com/api/mcp/projects/{project_id}",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Synaptic Code Intelligence safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Synaptic

Give your coding assistant a map of the codebase, not a pile of files.

Synaptic maps a repository once so you and your coding assistant do not have to rediscover it every session. Ask how a system works, what depends on a symbol, or what a change may break. The answers come from a persistent, source-grounded knowledge graph, available from the CLI or through MCP. Synaptic can also remember past changes and plan small, reviewable API and dependency repairs.

Code extraction is local and deterministic. Synaptic ships as a single Rust binary with no runtime, database, account, or API key required.

Documentation | Quickstart | Benchmarks | Discord

Get started

Install the latest checksummed release:

# macOS / Linux

curl --proto '=https' --tlsv1.2 -LsSf https://raw.githubusercontent.com/ColinVaughn/Synaptic/main/install.sh | sh

Windows PowerShell

irm https://raw.githubusercontent.com/ColinVaughn/Synaptic/main/install.ps1 | iex

Then run Synaptic from a repository:

synaptic extract .                         # build synaptic-out/graph.json

synaptic query "how does authentication work?" synaptic affected parse_config # what could this change break?

Extraction honors .gitignore and .synapticignore, skips common secret files, and stays offline unless you explicitly enable a network-backed feature.

Connect your coding assistant

synaptic install claude                    # Claude Code

synaptic install codex # Codex CLI synaptic install codex --global # Codex desktop app

Claude and Codex load only a small set of tools at startup, then find the rest on demand. This keeps prompts smaller without hiding capabilities. Gemini, Cursor, Copilot, OpenCode, Kilo, and generic AGENTS.md clients are supported too. See Assistant Integration.

What it does

Need	What Synaptic provides
Understand the code	Symbols, calls, imports, inheritance, resources, SQL, and cross-language boundaries in one graph
Find impact	Callers, references, reverse dependencies, dynamic-dispatch hazards, and affected tests
Change code safely	Change forecasts, refactor plans, architecture diffs, and optional verification in an isolated worktree
Remember the past	Source-linked history from commits, decisions, incidents, reviews, CI, and previous attempts
Maintain dependencies	API contract tracking and vulnerability evidence with small, reviewable repair workflows

Synaptic supports dozens of languages, incremental updates, multi-repository federation, structural search, SQL auditing, graph-aware PR review, and exports for GraphML, Cypher, Graphviz, Obsidian, and Markdown. Detailed capabilities live in the documentation, keeping this page focused on getting started.

See the architecture

synaptic chart

This creates a self-contained architecture map from the graph. Open a subsystem, select a symbol, and follow its real incoming and outgoing relationships without a server.

Built to save context

Synaptic returns the relevant slice of a graph instead of loading whole source files into an assistant's context. In the checked-in token benchmark, full graph answers used 27-38x fewer tokens than reading the source files referenced by those answers. That is a context-compression measurement, not a promise about total task cost. The methodology and raw results are in BENCHMARKS.md.

Common commands

Command	Purpose
`synaptic extract .`	Build the graph
`synaptic update` / `synaptic watch`	Keep it current
`synaptic query "..."`	Find the relevant subgraph for a question
`synaptic affected`	Trace reverse impact
`synaptic predict`	Forecast risk and select tests
`synaptic speculate`	Verify a change in a throwaway worktree
`synaptic memory search "..."`	Find relevant repository history
`synaptic serve`	Run the MCP server

Run synaptic --help for flags or use the complete command reference.

Pick a workflow

CLI: the fastest path for local extraction, queries, automation, and MCP.
Desktop: run synaptic-ui for visual repository setup, federation, assistant connection, updates, and the complete command catalog.
Hosted: Synaptic Cloud provides a managed MCP service. See the GitHub automation guide for commit-triggered graph sync and verified repair workflows.
