Petromcp MCP Server tools

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is Petromcp?

Petromcp is a local-first MCP server that lets Claude read LAS well log files directly. It wraps open-source parsers like lasio and exposes them as MCP tools, enabling natural conversation with petroleum data without copy-pasting curve values.

How to use Petromcp?

Requires Python 3.10+, uv, and Claude Desktop. After cloning the repo and running make setup and make install-claude, configure an allowlist of directories Petromcp can read using the CLI subcommands petromcp config init and petromcp config add-path. Restart Claude Desktop, then ask questions like "What's wrong with this well log?" in a new conversation.

Key features of Petromcp

  • MCP tools for reading, summarizing, and comparing LAS files
  • Unit conversion between common petroleum units (ft↔m, psi↔kPa, etc.)
  • Built-in qc_a_well_log prompt for standard QC workflow
  • Strict file allowlist – cannot read outside allowed directories
  • Zero telemetry, no automatic updates, runs entirely on your machine
  • Ships with synthetic sample data for testing without real files

Use cases of Petromcp

  • Diagnose well log quality issues by asking Claude to read and analyze a LAS file
  • Compare two wells for common curves, depth overlap, and unit consistency
  • Convert units (e.g., psi to kPa) during data interpretation
  • Walk through a standardized QC pass using the built-in prompt
  • Explore LAS files without installing specialized petroleum software

Frequently asked questions

1

How does Petromcp protect my data?

Petromcp runs locally and refuses to read any file outside an explicit allowlist you configure. It contains no telemetry, no phone-home, and no automatic updates.

2

What dependencies does Petromcp require?

It requires Python 3.10+, `uv` (the Astral package manager), and the Claude Desktop application.

3

Where does Petromcp store my data?

All data remains on your machine. Petromcp only reads files from directories you explicitly add to its allowlist via `petromcp config add-path`.

4

What file formats does Petromcp support?

Currently, Petromcp supports LAS well log files (v0.2). Support for DLIS, SEG-Y, and pump card data is planned for future releases.

5

How do I invoke Petromcp tools?

Once installed and configured, open a new conversation in Claude Desktop and ask plain-language questions about your well logs. Claude automatically selects the appropriate MCP tool (e.g., `read_las_file`, `summarize_las_curves`, `compare_well_logs`) and reads the file through Petromcp.
