macrostrat-mcp

MCP server for Macrostrat API

An MCP server implementation for providing access to the Macrostrat API within Claude Desktop.

Overview

This Model Context Protocol (MCP) server enables AI assistants and applications to:

• Query comprehensive geologic data and information provided by the Macrostrat API
• Access geologic units, columns, minerals, timescales, and more
• Get geologic map tiles that the LLM can interpret (questionable utility, but might be useful for some applications)
• Analyze geologic data to improve geological understanding
• Create graphics and perform data analysis from the data

Users can run queries using natural language.

Geological History of Nashville, Tennessee

1. Mesoproterozoic Basement (1.6-1.1 billion years ago)

• Igneous basement rocks (granite and rhyolite)
• Part of the ancient North American craton

2. Early-Middle Cambrian (518-504 million years ago)

• Rome Formation: Mixed carbonate-siliciclastic sediments
• Shallow marine environment
• Part of the developing continental shelf

3. Middle-Late Cambrian (504-498 million years ago)

• Conasauga Formation: Limestone and mixed sediments
• Continued marine deposition
• Alternating limestone and shale indicating fluctuating sea levels

4. Late Cambrian-Early Ordovician (498-470 million years ago)

• Knox Dolomite: Massive dolomite sequence
• Extensive shallow marine platform
• Up to 1,200 meters thick
• Represents long period of stable marine conditions

5. Middle-Late Ordovician (470-443 million years ago) Several important formations:

• Stones River Group (including Murfreesboro, Pierce, Lebanon Limestones)
• Nashville Group (including Hermitage, Bigby-Cannon, Catheys Formations)
• Primarily limestone deposits
• Rich in fossils
• Shallow marine environment
• Multiple cycles of sea level change

6. Early-Middle Silurian (443-423 million years ago)

• Brassfield through Decatur Formations
• Continued marine limestone deposition
• Various marine environments from shallow to deeper water

7. Middle Devonian-Early Mississippian (390-357 million years ago)

• Pegram Formation through Chattanooga Shale
• Shift to more clastic (shale) deposition
• Chattanooga Shale represents deeper, oxygen-poor conditions

8. Early-Late Mississippian (357-331 million years ago) Several limestone formations:

• Fort Payne Formation
• Warsaw Limestone
• St. Louis Limestone
• Monteagle Limestone
• Hartselle Formation
• Return to carbonate platform conditions
• Diverse marine environments

9. Cenozoic to Present

• Long period of erosion and exposure
• Development of the current landscape
• Formation of the Nashville Dome structure
• River and stream deposits

Key Features

• The area was predominantly a marine environment for most of its geological history
• Dominated by limestone formations indicating warm, shallow seas
• Multiple cycles of sea level change
• Rich fossil record, especially in Ordovician rocks
• Part of the Nashville Dome structural feature
• Long periods of erosion have removed younger rocks
• Current topography shaped by differential erosion of various limestone units

Present Day Bedrock

The bedrock of Nashville today consists primarily of Ordovician limestone format
