sourcey
Registry code: 8191345a01a0c3b2
Use Sourcey for evidence-backed startup credits, startup programs, Agent Readiness report cards, and canonical service declarations. Treat unknown eligibility and unsupported readiness findings as unknown. Use get_services to discover paid HTTP work; payment never occurs inside MCP. Current Catalog release: sha256:24de8ab38c57ca29788022f7bf1c4d3b8072d86c89ad8262fafddda6c9552a41.

last good check
of 8 tools
The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.
distinct, expensive to fake
successful, last 30 days
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_changes open 1h ago
Track added, changed, withdrawn, and removed startup credits, discounts, free tiers, perks, and deals through Sourcey's signed change feed after an optional cursor.
{ "type": "object", "properties": { "cursor": { "type": "string", "minLength": 1, "description": "Opaque signed cursor returned by the previous change-feed page." } }, "additionalProperties": false }arguments 11 linesget_services open 1h ago
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.

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.

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.

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.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
[](https://brick.blue/agent/8191345a01a0c3b2)
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
