How to Set Up and Use ArchMCP
ArchMCP is an architectural snapshot and knowledge graph MCP server that analyzes codebases to extract modules, symbols, dependencies, and routes into a structured graph representation accessible to AI agents. It exposes tools for generating architectural snapshots, querying dependency facts, exploring modules, traversing call graphs, and performing impact analysis — helping AI assistants understand complex codebases before making changes. Developers can use it to answer questions about architecture, identify cyclic dependencies, and plan refactors with full structural context.
Prerequisites
- Go 1.21 or higher installed to build the server binary
- An MCP-compatible client such as Claude Desktop or Cursor
- A codebase to analyze (supports Go, Python, TypeScript, and other languages)
- Optional: a configuration YAML file to specify repo paths, ignore patterns, and active extractors
Clone the repository
Clone the archmcp repository to your local machine.
git clone https://github.com/dejo1307/archmcp.git
cd archmcpBuild the archmcp binary
Compile the Go source into an executable binary using the Go toolchain.
go build -o archmcp ./cmd/...Create a configuration file
Create a YAML configuration file that points the server at your codebase and specifies any directories to ignore during analysis.
# mcp-arch.yaml
repo: /path/to/your/project
ignore:
- vendor
- node_modules
- .git
extractors:
- go
- typescript
output:
dir: /tmp/archmcp-snapshotsGenerate an initial snapshot
Run the server with your config file to generate the first architectural snapshot of your codebase.
./archmcp --generate mcp-arch.yamlConfigure Claude Desktop
Register archmcp as an MCP server in your Claude Desktop configuration, passing the config file path as an argument.
{
"mcpServers": {
"archmcp": {
"command": "/path/to/archmcp/archmcp",
"args": ["/path/to/mcp-arch.yaml"]
}
}

Client configuration
Claude Desktop configuration for the ArchMCP server with a YAML config file pointing at your project.
{
"mcpServers": {
"archmcp": {
"command": "/path/to/archmcp/archmcp",
"args": ["/Users/yourname/projects/myapp/mcp-arch.yaml"]
}
}
}Prompts to try
Example prompts for architecture exploration, dependency analysis, and impact assessment.
- "Generate an architectural snapshot of my project and summarize the main modules"
- "What packages would I need to modify to add a new REST API endpoint?"
- "Are there any cyclic dependencies or architectural layer violations in the codebase?"
- "Traverse the dependency graph from the AuthService and show everything that depends on it"
- "Perform an impact analysis: if I change the UserRepository interface, what breaks?"Troubleshooting ArchMCP
go build fails with module not found errors
Run 'go mod tidy' to download and resolve all module dependencies before building. Ensure your Go version is 1.21 or higher by running 'go version'.
Snapshot generation completes but the knowledge graph is missing many symbols
Check your mcp-arch.yaml configuration — ensure the 'repo' path is correct and the right extractors are listed for your language stack. Verify that the directories containing source files are not accidentally excluded by ignore patterns.
Claude Desktop does not see the archmcp tools after restarting
Confirm the absolute path to the archmcp binary in the 'command' field is correct and that the binary is executable (run 'chmod +x /path/to/archmcp'). Also verify the YAML config file path passed in 'args' exists and is readable.
