Sourcey MCP · Sourcey

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 reads Agent Readiness report cards, reads the State of Startup Credits and State of Agent Readiness reports, and prepares canonical Agent Readiness declarations for vendor services without assigning ratings. It never applies for or redeems an offer.

This server reads Sourcey’s research records. To generate reference documentation for an MCP server you build, use the open-source docs engine.

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 Track added, changed, withdrawn, and removed startup credits, discounts, free tiers, perks, and deals through Sourcey's signed change feed after an optional cursor.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. Each card grades one named job on a vendor's service by where a person or the vendor has to step in on an agent's path to it, from its listing and from probes that send the job's request with no account (or, where its interface has no public endpoint, read the vendor's OpenAPI document for it): one letter, A+ to F, over Discover, Authority, Onboard, Pay, Confirm and Sustain, and how often a person is needed; whether the job itself is reachable, verified by a fresh run (proof only, which never changes a step or the letter), or has no machine interface; beside the letter, the failure the vendor's own runs reproduce, when they do; the evidence label; freshness; and the canonical report URL. Service readiness is separate from startup-credit eligibility.
get_readiness · Get an Agent Readiness report card. Get one published Agent Readiness report card: the job and the interface whose path it grades (none for an F card whose listing names no interface), the letter and its statement, each step's outcome, approvals and human workarounds, the evidence label (probed, or the job verified by a run), the proof field when the vendor's own runs reproduce a failure of the job (which never moves the letter), discovery facts from the service's own descriptors and llms.txt, the declared surface, policy identity, provenance, and canonical URL. Resolve by immutable profile ID or by one Entity plus exact product and job.
get_report · Get a Sourcey report. Get the State of Startup Credits or the State of Agent Readiness report: the figures of one Catalog release (offers by size, by how a startup reaches them and by their terms; report cards by grade, by step and by category), that release's names for every company, offer and report card the figures cite, the fact sheets the prose was written from, and the prose itself, every sentence judged against those fact sheets. Without a release, the current report, written at most once a day from the release current then; with one, the report as written from that release, kept for citing. Each answer carries the page it is read at.
prepare_declaration · Prepare an Agent Readiness declaration. Prepare the canonical Agent Readiness declaration for one service and job: participants, endpoints, API and MCP interfaces, the job operation on each interface that performs the job (the request the probes send with no account, or the operation in the vendor's OpenAPI document where the interface has no public endpoint), and optional job bindings for a verified run. The company must already exist in Sourcey and resolves by exact identity; an unknown company returns identity_allocation_required. Complete declarations use POST /v1/submissions as product agent_readiness. Drafts grant no publication, verification or grade, and startup credits and deals never count as service readiness.
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.
