Overview

Description from the maker (original English)

MCP server providing log snippet and Python traceback extraction tools.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

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": {
    "logdetective": {
      "command": "uvx",
      "args": [
        "logdetective-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add logdetective -- uvx logdetective-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "logdetective": {
      "command": "uvx",
      "args": [
        "logdetective-mcp"
      ]
    }
  }
}

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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "logdetective": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "logdetective-mcp"
      ]
    }
  }
}

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.

Common questions

Is Log Detective MCP 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 (0.7.0) reached the registry 6 days 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?

Log Detective MCP

MCP server implementing core log analysis tools of Log Detective for use by other agents.

The server uses the Drain3 algorithm to cluster log messages into templates and extract a representative subset of snippets, reducing large logs to a manageable size for downstream analysis.

Installation

Requires Python 3.11+.

pip install .

Or with uv:

uv pip install .

Usage

Running the server
logdetective-mcp

Or directly:

python -m logdetective_mcp.main
MCP client configuration
Claude Code
claude mcp add logdetective -- logdetective-mcp
Claude Desktop

Add to your Claude Desktop configuration file:

{

"mcpServers": { "logdetective": { "command": "logdetective-mcp" } } }

Tools

extract_log_snippets

Extracts representative log snippets using Drain3 clustering. The tool chunks the log into logical messages, clusters similar messages, and returns one representative snippet per cluster.

Log content can be provided in three ways (exactly one must be used):

ParameterTypeDescription
log_textstrRaw log text passed directly.
log_pathstrPath to a log file on the server's filesystem.
log_urlstrHTTP(S) URL to fetch log content from.

The input schema for both tools uses oneOf to require exactly one nonempty source field. Omitted source fields and fields set to "" do not count as a source. This matches the rule checked when a tool runs. The advertised tool definitions conform to the MCP 2025-11-25 Tool schema.

Optional parameters:

ParameterTypeDefaultDescription
max_clustersint8Maximum number of snippets to extract.
max_snippet_lenint2000Maximum character length per snippet.
skip_patterns`list[str] \null`nullList of regex patterns. Chunks matching any pattern are excluded before clustering.
contextint0Number of lines to include before and after each snippet (0-50).

Returns a list of Snippet objects, each with line_number (position in the original log) and text (the extracted snippet content). MCP structured output wraps this list as {"result": [...]}; the advertised output schema describes that object.

extract_python_tracebacks

Extracts Python tracebacks from the log, including chained exceptions.

ParameterTypeDefaultDescription
max_traceback_lenint2000Maximum character length per extracted traceback.
skip_patterns`list[str] \null`nullList of regex patterns. Tracebacks matching any pattern are excluded.
contextint0Number of lines to include before and after each traceback (0-50).

For both extractor tools, context follows grep's -C behavior: the requested number of surrounding log lines is included on each side when available. The length limit applies to the extracted snippet or traceback; context lines are additional, so the returned text can be longer than the limit. With context enabled, line_number points to the first returned line. Values outside 0-50 are rejected.

If a traceback is truncated, the extractor keeps its beginning and end with a marker when max_traceback_len permits; smaller limits keep only a prefix. Following context starts after the original traceback, without restoring its omitted middle. If a log line is split into chunks by max_snippet_len, each selected chunk keeps its own text when context is added. Neighboring lines do not replace it with the complete long line. Context boundaries follow the chunk's original source lines, including blank lines omitted from the rendered chunk.

Size limits

All downloaded inputs (via log_url) are limited to 100 MB regardless of format. Downloads are streamed in chunks and aborted as soon as the limit is exceeded.

Archives read via log_path are also checked against the 100 MB limit during decompression.

Compressed file support

Both tools transparently decompress archived log files. Supported formats:

  • Single-file compression: .gz, .bz2, .xz, .lzma
  • Archives: .zip, .tar, .tar.gz, .tar.bz2, .tar.xz

Format is detected from the file extension (or URL path). Archives must contain exactly one file.

Zip bomb protection is enforced via:

  • Maximum decompressed size of 100 MB
  • Maximum compression ratio of 100:1
  • Pre-check of declared sizes in zip/tar headers
  • No recursive decompression (nested archives are not unpacked)

Contributing

All changes to this repository must pass pre-commit checks and tests.

uv run pytest tests/

To inspect the JSON schemas returned by the installed server, run the check script with the project's virtual environment. It starts the server over MCP stdio, validates both tool schemas and structured results, and compares the returned tool definitions with the files in schemas/:

.venv/bin/python scripts/check_mcp_schemas.py

After an intentional schema change, regenerate those files with:

.venv/bin/python scripts/check_mcp_schemas.py --write
