What you can do with it
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
- Connection: Runs on your computer
- Transport: stdio
- Category: Developer tools
Install
Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- The registry lists no key to fill in.
You need
- PyPIPython’s uv installed (for the uvx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"repo-mapper": {
"command": "uvx",
"args": [
"mcp-repo-mapper"
]
}
}
}Run this in your terminal
claude mcp add repo-mapper -- uvx mcp-repo-mapperOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"repo-mapper": {
"command": "uvx",
"args": [
"mcp-repo-mapper"
]
}
}
}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.
Or copy the settings yourself
Paste into .vscode/mcp.json in your project
{
"servers": {
"repo-mapper": {
"type": "stdio",
"command": "uvx",
"args": [
"mcp-repo-mapper"
]
}
}
}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.
This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.
Your choice stays on this device in a cookie; no account needed.
These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
What it can do

Common questions
Is MCP Repo Mapper 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 6 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?
In the same category: GitHub, Desktop Commander, Cloudflare MCP

mcp-repo-mapper
mcp-repo-mapper is a FastMCP server for deterministic repository structure mapping. It scans a local codebase and exposes file structure, language counts, Python import dependencies, circular dependency detection, framework detection, entry point candidates, and a cached repo structure resource.
The server does not call an LLM and does not execute user code. It is intended as a grounded structure tool for codebase onboarding agents such as wayfinder.
Codebase Onboarding Stack
mcp-repo-mapper is the structure layer in a three-server MCP tool stack for Project 6 wayfinder, a codebase onboarding agent.
mcp-repo-mappermaps repository structure, languages, entry points, framework evidence, and Python dependency edges.mcp-ast-explorerprovides symbol-grounded Python definition, signature, reference, call-chain, and class-hierarchy lookups.mcp-test-runnerruns local pytest/Jest checks and coverage summaries so agent claims can be verified against execution.
In wayfinder, this server feeds the architecture-mapping step before semantic explanation or test verification begins.
Features
scan_repo(path)returns a typed repo scan with files, language breakdown, entry points, Python dependency graph, and detected frameworks.find_circular_deps(path)returns circular dependencies from the static dependency graph.language_breakdown(path)returns language counts by file count and bytes.detect_framework(path)detects FastAPI, Flask, Django, Express, and Spring using registry-based markers.find_entry_points(path)returns ranked entry point candidates such as Python mains, FastAPI apps, package start scripts, Dockerfiles, and Node indexes.repo-structure://{url_hash}returns a cached JSON scan result after a tool call has populated the cache.
Install
uv sync --extra devRun the server locally:
uv run mcp-repo-mapperDevelopment
uv run ruff check .uv run mypy uv run pytest
Resource Flow
Resource reads use a cache populated by tool calls:
- Call
scan_repo(path)or another scan-backed tool. - Compute the repo hash with the same path.
- Read
repo-structure://{url_hash}.
The public resource uses repo-structure://... because URL schemes cannot contain underscores.
Scope And Limitations
- Dependency graph support is currently Python-only and based on static
astparsing. - Import graph resolution only records modules that exist inside the scanned repo.
- Framework detection is heuristic marker matching, not a full build-system analysis.
- The resource cache is in-memory and process-local.
- The server scans local filesystem paths only.
