### Description (declared)

# Cosmos SDK Migration MCP Server

An MCP (Model Context Protocol) server for migrating Cosmos SDK chains from
`v0.50+` to `v0.54`.

This repository packages the migration server, the YAML migration specs, the
orchestration guide, and the bundled upgrade-doc resources it exposes over MCP.

## Install

```bash
pip install cosmos-migration-mcp
```

Or for local development:

```bash
git clone https://github.com/cosmos/cosmos-sdk-migration-mcp.git
cd cosmos-sdk-migration-mcp

```bash
cosmos-migration-mcp
```

You can also run it as a module:

```bash
python -m cosmos_migration_mcp
```
