What is the Co MCP server?

MCP server for Colombian Constitutional Court case law (datos.gov.co), citation verification. The co mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.

What it actually does

MCP server for the datos.gov.co open-data record of decisions (sentencias) by the Colombian Constitutional Court (Corte Constitucional). Verifies whether a citation exists and returns its metadata.

Its toolset

Everything the assistant can do here goes through one of these:

  • co_search_sentencias — Free-text search (e.g. by magistrado name or proceso type)
  • co_get_sentencia — Exact lookup by citation, e.g. "T-012/92" - verifies it exists

Configuration

You will need one environment variable: CO_ELI_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at co-eli-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Co's toolset — co_search_sentencias, co_get_sentencia — is a fair guide to whether it matches your workflow. It is maintained by matematicsolutions; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the co mcp server does with a few real requests.

How to install the Co MCP server

{
  "mcpServers": {
    "co-eli": {
      "command": "uvx",
      "args": ["co-eli-mcp"],
      "env": {
        "CO_ELI_BASE_URL": "your-value"
      }
    }
  }
}

Add to claude_desktop_config.json, then restart Claude Desktop.

Example prompts to try

  • Use Co to co search sentencias.
  • Use Co to co get sentencia.

Frequently asked questions

It connects Co to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (co_search_sentencias, co_get_sentencia) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Co directly.
