# Sourcey

A hosted MCP server that finds startup credits and deals, shows the terms behind them, and serves Agent Readiness report cards.

## What it does

Sourcey plugs into your agent as a remote server at `https://mcp.sourcey.com/mcp`. From there the agent searches current credits, discounts and free tiers for startups, lines offers up against each other, and reports where each term came from and when it was last checked. Agent Readiness cards are separate: visible grades, findings across five stages, blockers and fixes.

Clients that insist on a local command can use the thin bridge `npx -y @sourcey/mcp-server`. It ships no offer dataset and implements no tools itself. On start it talks to the live Sourcey server, pulls the tool definitions once, then forwards calls. Data changes therefore land without a new package release.

The Claude plugin talks only to the public HTTPS server and needs no local credential. Gemini CLI users can instead run `gemini extensions install https://github.com/sourcey/mcp-server --ref main`; drop `--ref main` and Gemini CLI falls back to the older v1.0.0 archive, which has no extension manifest. `SOURCEY_MCP_URL` points at a different HTTPS Sourcey endpoint. Plain HTTP is allowed for a loopback test server only, and URLs carrying credentials or fragments are rejected. No payment happens inside MCP.

## When to use it
- find live startup credits and discounts
- compare two offers by their recorded terms
- tell confirmed conditions from unverified ones
- read an Agent Readiness card and its blockers
- draft an Agent Readiness declaration in YAML without a grade

## Example prompts
- Find current cloud-hosting startup offers in Sourcey. For three of them show the original source, the last-checked date and any eligibility unknowns.
- Pull up an Agent Readiness report card and walk me through the tested workflows, the blockers and the claims still unverified.
