Search volunteer opportunities across Spain via hacesfalta.org
Overview
Searches volunteer opportunities across Spain on hacesfalta.org, letting an assistant find and detail listings by province, category and schedule.
- What you can do
- Search volunteer opportunities by province, category, frequency, schedule, age, weekend, family or group, with paginated results and sign-up links
- Read the full detail of one opportunity: description, sought profile, dates, hours, skills, SDGs and sign-up link
- List all volunteering categories with the number of opportunities in each
- List all Spanish provinces that have volunteer opportunities
- When to use it
- Useful when someone wants conversational help finding volunteering in Spain, for example matching a city, cause and weekend availability to real listings with sign-up links.
- Requirements
- Runs as a local Node.js process from the npm package, or as a remote MCP endpoint. Requires the HACESFALTA_API_URL base URL and the HACESFALTA_API_KEY secret, both set as environment variables. Network access to the HaceFalta API.
Installation
In SourceWeft
- Open Hacesfalta Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
