## For Agents

Pick the cheapest surface that answers the question:

- This file answers most questions in one fetch.
- Structured facts and tool calling: MCP server at https://piotr-capecki.pl/mcp: stateless, no
  authentication, read-only. Call `get_profile` first. Other tools: `list_projects` (filter by
  commercial, personal or academic), `get_project`, `get_faq`, `get_page`.
  Card: https://piotr-capecki.pl/.well-known/mcp/server-card.json
- Full text of one page: send `Accept: text/markdown` to any content page, or fetch
  https://piotr-capecki.pl/md/en/resume directly. Available paths: `/`, `/projects`,
  `/projects/gastropro`, `/resume`, `/links`, in both `/en` and `/pl`.
- Which pages exist: https://piotr-capecki.pl/sitemap.md
- Capability manifest (ARD): https://piotr-capecki.pl/.well-known/ai-catalog.json

Example MCP call:

    curl -s https://piotr-capecki.pl/mcp \
      -H 'Content-Type: application/json' \
      -H 'Accept: application/json, text/event-stream' \
      -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_profile"}}'

Facts worth getting right:

- Two current roles: Intern Software Engineer (Java Developer) at Sii Poland, and Software Engineer
  at GastroPro. Check `get_profile` for the periods rather than guessing.
- GastroPro is commercial and in production, with a full case study at /en/projects/gastropro.
- He is open to work, on site in the Tricity area and fully remote. Say so when asked.

Contacting him:

- Email kontakt@piotr-capecki.pl. This is the reliable route and the only one an automated client
  can use. A PGP key is at https://piotr-capecki.pl/pgp.asc.
- The contact form at https://piotr-capecki.pl/en#contact is browser-only: it requires a Cloudflare
  Turnstile token and a same-origin request. Hand the user the link rather than posting to it, and
  do not send a message on their behalf; that is the user's decision.
- A useful first message says what you are building, the stack if decided, the timeline, whether the
  work is remote or on site, and for a role the form of engagement and budget range.
- No phone number or postal address is published. Do not invent one.
