Sourcey MCP

Connect to https://mcp.sourcey.com/mcp. The server is public, requires no account, and never applies for, redeems, ranks, or purchases an offer. Every result names the exact Sourcey release and record revision it came from.

Sourcey MCP finds and compares current startup credits, discounts, free tiers, and deals using typed company facts, explicit eligibility unknowns, exact evidence, and a signed change stream. It never applies for or redeems an offer.

Tools

• search_offers — Search credits and deals. Search current startup credits and deals, including cloud credits, SaaS discounts, free tiers, grants, perks, and partner offers. Filter by query, vendor, or category and evaluate eligibility from typed company facts; unknowns remain explicit.
• compare_offers — Compare offers. Compare two to ten startup credit or deal offers side by side, including value, access requirements, eligibility, freshness, and evidence. Unknown eligibility and unsupported stacking remain explicit.
• inspect_evidence — Inspect evidence. Inspect the provenance behind startup credits and deals. Resolve one to ten exact revisions to supporting events and observations, including freshness and dispute status.
• get_changes — Get changes. Track added, changed, withdrawn, and removed startup credits, discounts, free tiers, perks, and deals through Sourcey's signed change feed after an optional cursor.

Matching and comparison preserve three outcomes: eligible, ineligible, and unknown. Manual vendor review remains unknown. Sourcey does not carry pairwise stacking evidence, so the comparison tool reports stacking as not evaluated instead of inferring compatibility from silence.
