Measured tools (9)

• search_offers read-only

  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.

  Parameters:

  • facts (required) — object — Known typed company facts used only for explicit eligibility evaluation; omit unknown facts.
  • limit — integer — Maximum results to return; defaults to 10.
  • query — string — Natural-language search for a startup need, technology, credit, discount, free tier, perk, grant, or deal.
  • entities — array — Current Entity slugs or immutable Entity IDs to include.
  • categories — array — Catalog categories to include, such as hosting, databases, or observability.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• compare_offers read-only

  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.

  Parameters:

  • offers (required) — array — Two to ten exact startup credit or deal offers to compare in this order.
  • facts (required) — object — Known typed company facts used only for explicit eligibility evaluation; omit unknown facts.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• inspect_evidence read-only

  Inspect the provenance behind startup credits and deals. Resolve one to ten exact revisions to supporting events and observations, including freshness and dispute status.

  Parameters:

  • revision_digests (required) — array — Exact offer revision digests returned by Sourcey search or comparison.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_changes read-only

  Track added, changed, withdrawn, and removed startup credits, discounts, free tiers, perks, and deals through Sourcey's signed change feed after an optional cursor.

  Parameters:

  • cursor — string — Opaque signed cursor returned by the previous change-feed page.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_readiness read-only

  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.

  Parameters:

  • job — string — Exact Agent Readiness job key from the job library.
  • label — string — What the job's outcome rests on: probed (the listing and the probes) or vendor_run_verified (a fresh run on an account holder's own runner did the job, and Sourcey replayed and verified it).
  • limit — integer — Maximum results to return; defaults to 10.
  • query — string — Vendor, service, API, product, or job.
  • entity — string — Current Sourcey Entity slug or immutable Entity ID.
  • letter — string — Exact published letter.
  • product — string — Exact Agent Readiness product key.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_readiness read-only

  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.

  Parameters:

  • job — string
  • entity — string — Current Sourcey Entity slug or immutable Entity ID.
  • product — string
  • profile_id — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_report read-only

  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.

  Parameters:

  • report (required) — string — Which report: startup-credits (what startup offers give, who can get them and what they ask in return) or agent-readiness (whether an agent can do a software job on its own, and where a person has to step in).
  • release_id — string — The release a report was written from, to read it as cited; omit for the current report.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• prepare_declaration read-only

  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.

  Parameters:

  • command_contract (required) — string
  • scope_source_uris (required) — array
  • subject_roles (required) — array
  • job_operations (required) — array
  • job_bindings (required) — array
  • participants (required) — array
  • resources (required) — array
  • endpoints (required) — array
  • interfaces (required) — array
  • relations (required) — array
  • offer_relations (required) — array
  • surface_exclusions (required) — array
  • scope — object
  • subject
  • declared_at — string
  • authority_intent — string
  • account_operations — array
  • base_authoring_file — object

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_services read-only

  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.
