MCP Connector — SEIA (SEA Chile)

MCP (Model Context Protocol) server that gives Claude a tool to look up RCA/ICSARA documents of an SEIA project directly from a regular chat (Claude app, Claude Code, or any MCP client) — without having to run any script.

It reuses the same mechanism already proven in the MVP2 of the internship (acta-web/api/buscar-documentos.mjs): an internal endpoint at seia.sea.gob.cl that retrieves all the documents of a case file without login.

What it does (for now)

A single tool: buscar_documentos_seia. It takes a project's id_expediente and returns its RCA and ICSARA documents (type, date, link). It's read-only on public SEA information — it doesn't use any API key and has no cost, so the connector remains unauthenticated for now.

It does not include AI extraction (Gemini) yet — that was intentionally left out because that part does have a cost/quota, and if the connector URL were left public without protection, anyone could spend it. It can be added later if needed, with authentication.

Publishing it (one time only)

Step 1 — Create the repo on GitHub

Just like with acta-web: github.com/new, name it sea-mcp, empty (no README or .gitignore), and send me the URL so I can upload the code.

Step 2 — Connect it to Vercel

1. In Vercel: Add New → Project → Import the sea-mcp repo.

2. Vercel automatically detects that it's Next.js — no further configuration is needed.

3. It gives you a URL like https://sea-mcp.vercel.app.

Step 3 — Add it as a connector in the Claude app

1. In claude.ai: Settings → Connectors → Add custom connector.

2. Paste the URL: https://sea-mcp.vercel.app/api/mcp

3. Save. You should now be able to ask Claude, in a regular chat, something like "search for the RCA and ICSARA documents of the case file 2160034555" and have it use the tool directly.

Test it before connecting to Claude (optional)

With the MCP Inspector: point it to https://sea-mcp.vercel.app/api/mcp with the "Streamable HTTP" transport, click "List Tools" and test buscar_documentos_seia with id_expediente: 2160034555 (Parque Eólico Wayra, already used as a real test case in MVP2).
