We couldn’t confirm it starts correctly

We ran the install command but it didn't respond within our test window — this can mean a slow first-time install rather than a real problem.

npx -y depwire-cli

No response to initialize.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 29d ago.

Overview

depwire/depwire MCP server gives AI coding assistants deterministic dependency context for a codebase. It uses tree-sitter to parse symbols and relationships across 17 programming languages, then exposes the resulting graph through MCP tools. Use it when an agent needs symbol-level impact analysis, change simulation, security checks, or architecture context before editing code. Processing runs locally, and the security scanner does not require an API key.

Use cases

  • Inspect symbol-level dependency relationships before editing code
  • Simulate the blast radius of deleting or changing a symbol
  • Scan a local repository for security issues without an API key
  • Visualize repository architecture and dependency structure
  • Compare structural changes between commits

Key features

  • Deterministic tree-sitter dependency parsing
  • MCP access to local codebase graph data
  • What-if impact simulation
  • Dead code detection and health scoring
  • Security scanning without an API key
  • Multi-language and cross-language analysis

How Depwire works

What depwire/depwire does

The depwire/depwire MCP server maps a repository at symbol level rather than only tracking packages or files. Its graph includes functions, classes, interfaces, imports, exports, and related dependency edges. This lets an AI coding assistant inspect how a proposed change may affect other parts of the codebase.

Parsing is based on tree-sitter and is described as deterministic rather than embedding- or retrieval-based. The project lists support for 17 languages, including TypeScript, JavaScript, Python, Go, Rust, C, Java, PHP, Ruby, Dart, R, C++, C#, Kotlin, Swift, and Mojo. The repository also identifies HTML and Angular support.

How it works

The depwire/depwire MCP server builds a local dependency graph from source files and makes focused graph information available through MCP. An agent can use that context instead of requesting broad file contents when it needs to understand callers, imports, exports, or likely downstream effects.

The repository describes the graph as symbol-level, which distinguishes it from build tools that generally represent package-level relationships. Its analysis includes what-if simulations for evaluating a proposed deletion or change, structural comparisons between commits, and pre-action verification. A temporal graph can represent how the code structure changes over time.

The project states that code parsing runs on the local machine and that source code is not sent to a cloud service. Its security scanner does not require an API key. The README also cautions that previously published benchmark conclusions were withdrawn after an audit, so those results should not be used to assess performance or correctness.

Setup and configuration

Install the command-line package globally with:

Terminal
npm install -g depwire-cli

The documented commands include:

bash
depwire whatif
depwire security
depwire viz

These commands respectively support change-impact simulation, security analysis, and architecture visualization.

Tools and capabilities

The depwire/depwire MCP server provides MCP access to dependency-graph data and related analysis. Supported capabilities described in the repository include:

  • Symbol- and import-level dependency inspection
  • What-if analysis for proposed code changes
  • Dead code detection
  • Architecture health scoring
  • Security scanning without an API key
  • Arc diagram visualization
  • Temporal graph analysis
  • Structural diffs between commits
  • Pre-action verification for AI-generated changes
  • Cross-language edge detection

The project describes the MCP interface as providing 24 tools in its README badges and infrastructure section.

Limitations and notes

Results depend on the parser’s language support and the source structure it can analyze. The repository reports that parser fixes in version 1.9.0 changed symbol counts, edge counts, and health scores for several languages, so older example measurements should not be treated as exact for current versions.

The package is licensed under BUSL-1.1.
