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 also prepares canonical Agent Readiness declarations for vendor APIs, SaaS services, authentication, payment, provisioning, operation, recovery, and agent standards without assigning readiness results. 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 Track added, changed, withdrawn, and removed startup credits, discounts, free tiers, perks, and deals through Sourcey's signed change feed after an optional cursor.
• search_readiness · Search Agent Readiness. Search published Agent Readiness report cards for APIs, SaaS products, authentication, payments, provisioning, operations, and recovery. Returns the overall A+ to F grade, five-stage outcomes, evidence coverage, freshness, primary blocker, remediation context, and canonical report URL without conflating service readiness with startup-credit eligibility.
• get_readiness · Get an Agent Readiness report card. Get one exact published Agent Readiness report card with its visible A+ to F grade, five service-use stages, individual findings, blockers, remediations, tested surfaces, methods, evidence state, coverage, freshness, policy identity, provenance, and canonical URL. Resolve by immutable profile ID or by one Entity plus exact product and funnel.
• prepare_declaration · Prepare an Agent Readiness declaration. Prepare canonical GitHub-ready YAML for an independent Agent Readiness assessment of one vendor product, API, SaaS service, authentication path, payment path, provisioning flow, operating interface, recovery flow, and exact agent standard. Resolves only exact Sourcey Entity identity, never assigns a grade or treats startup credits and deals as service readiness, and returns precise missing fields when the service graph is incomplete.
• get_services · Get Sourcey paid services. Discover Sourcey's enabled paid agent services and canonical HTTP resources, including exact request and response contracts, price floor, policy links, and x402 discovery. Payment and durable job status remain on the product HTTP API; this read-only MCP tool never signs, settles, or interprets a payment.

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.

Evidence labels

Evidence on record means Sourcey retained dated evidence under the catalog policy. Vendor confirmed means a principal with current vendor authority attested to that exact revision. Verified company applies only to the company identity Sourcey checked. Terms checked applies only to the exact Offer revision Sourcey checked. Agent Readiness remains a separate assessment.
