### Description (declared)

# dhis2w-mcp-bridge

A FastMCP server that exposes the entire `d2w` CLI as **one** MCP tool, `dhis2_cli`.

Where `dhis2w-mcp` registers ~304 typed tools (≈50-65k tokens of schema loaded into the
model's context up front), this server registers a single tool that shells out to the local
`d2w` binary. A small, context-limited **local model** discovers the command surface
progressively with `--help` and runs commands with `--json` — and nothing leaves the host.

## Why this exists

For sensitive data that must stay on-box, you run a local model (LM Studio, Ollama,
llama.cpp). Such models can't spare ~53k tokens for tool schemas, and many degrade when
choosing among hundreds of tools. One tool + on-demand `--help` fits an 8k-context model and
keeps the full DHIS2 surface reachable. Same code as the CLI — the bridge just runs it.

Use `dhis2w-mcp` (the full typed server) for hosts that do progressive tool disclosure
themselves (e.g. Claude Code handles all 304 tools fine). Use this bridge for small local
models.

## The tool

```
dhis2_cli(args: list[str], profile: str | None = None) -> CliResult
CliResult = { exit_code: int, stdout: str, stderr: str }
```

The model is expected to discover, then act:

```
dhis2_cli(["--help"])                                  # list command groups
dhis2_cli(["metadata", "--help"])                      # drill into a group
dhis2_cli(["metadata", "list", "dataElements",
           "--filter", "name:ilike:malaria"])          # run a command
```

Contract: `--json` is injected automatically, so on success (`exit_code == 0`) `stdout` is
JSON. `--help`/`--version` exit 0 with human text. Any non-zero exit is a failure and the
message is on `stderr` (never JSON). `profile` is injected as `-p <profile>`.

## Install & run

The bridge depends on `dhis2w-cli`, so installing it provides the `d2w` binary.

```bash
# From a workspace checkout (development)
uv run dhis2w-mcp-bridge

# From PyPI
uv tool install dhis2w-mcp-bridge
dhis2w-mcp-bridge
```…
