Hudu MCP Server

An MCP server for the Hudu API (v1), the IT documentation platform MSPs use per client. It lets an AI agent read companies, documented assets and their layouts, stored passwords, knowledge-base articles and folders, monitored websites, procedures, relations, Magic Dash tiles and the activity (audit) log and, on explicit request, create, update and archive records and (with confirmation) delete them.

• Transport: MCP Streamable HTTP at POST /mcp, health probe at GET /health

• Stateless and multi-tenant: credentials arrive on every request as HTTP headers and are never stored; every tool is listed from the first tools/list

• Python 3.12, uv, FastMCP, httpx

Authentication headers

Where to get them: in Hudu open the Admin area's API key settings and create a key. Use the key options Hudu offers (such as limiting the key or its access to passwords) to give the agent only what it needs. If Hudu restricts API access by IP, allow the public egress IP of the environment that runs this server.

How the key is sent to Hudu: every call goes to {X-Hudu-Base-URL}/api/v1/... with the key in the x-api-key header.

A request to /mcp without both headers gets HTTP 401 naming the missing one; a non-https URL gets HTTP 400.

Tools

All tools return a JSON string. List tools take page and page_size (default 25, max 1000) and return {count, page, has_more, next_page}. write marks tools that change data; confirm marks deletes, which also need confirm: true.

Errors come back as a JSON envelope instead of an exception:

{"error": {"code": "invalid_argument", "message": "Hudu returned HTTP 422 for companies: name has already been taken", "retryable": false}}

code is one of not_configured, unauthorized, not_found, invalid_argument, rate_limited, upstream_error. Reads are retried with backoff on 429, 5xx and network errors; writes only on 429. Hudu allows about 300 API requests per minute per instance.

Run locally

uv sync
uv run python -m hudu_mcp          # listens on 0.0.0.0:8080

or with Docker:

docker build --platform linux/amd64 -t hudu-mcp:dev .
docker run --rm -p 8080:8080 hudu-mcp:dev

Configuration (environment variables, all optional): MCP_HTTP_HOST (default 0.0.0.0), MCP_HTTP_PORT (default 8080), LOG_LEVEL (default INFO). Credentials are never read from the environment.

Testing example

# list tools
curl -s http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "X-Hudu-Base-URL: https://docs.example.com" \
  -H "X-Hudu-API-Key: your-hudu-api-key" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

# assets of one company
curl -s http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "X-Hudu-Base-URL: https://docs.example.com" \
  -H "X-Hudu-API-Key: your-hudu-api-key" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"hudu_list_assets","arguments":{"company_id":12}}}'

Unit tests (no network access needed):

uv run pytest

Delivery notes

• Tool count (39). Kept as is because the tool names are an existing contract.

• Asset routes fixed. Hudu serves single assets only under their company (/companies/{company_id}/assets/{id}); older versions called /assets/{id}, which does not exist, so getting, updating, deleting and archiving assets failed. The four tools now take an optional company_id and look it up from the asset id when it is omitted.

• Password handling. hudu_list_asset_passwords returns entries with password and otp_secret masked (plus has_password / has_otp_secret), so a company's credentials are not all exposed at once; hudu_get_asset_password reveals one entry. Create / update results are masked too.

• Deletes need confirmation. The five delete tools take confirm: true and otherwise return a "not done" result; archiving is the reversible alternative.

• Websites. Hudu stores the website address as its name; the old url parameter, which the API ignores, was dropped. The websites list has no server-side company filter, so company_id filters the returned page.

• Request bodies are wrapped in the resource name Hudu expects ({"company": {...}}, {"asset": {...}}, ...).
