How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1471 tokens (~163/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
- Stability check failed: schema churn in the 29 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 1 additions. See how to fix → Fail
Tool Coverage85
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 48% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

get_readiness Get an Agent Readiness report card ~173
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 ~221
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.

get_services Get Sourcey paid services ~66
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.
Input schema present but exposes no named parameters.

prepare_declaration Prepare an Agent Readiness declaration ~280
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.
| Name | Type | Req | Description |
|---|---|---|---|
| account_operations | array | – | – |
| authority_intent | string | – | – |
| base_authoring_file | object | – | – |

search_offers Search credits and deals ~161

| Name | Type | Req | Description |
|---|---|---|---|
| categories | array | – | Catalog categories to include, such as hosting, databases, or observability. |
| entities | array | – | Current Entity slugs or immutable Entity IDs to include. |

| release_id | string | yes | – |
| total | integer | yes | – |
| truncated | boolean | yes | – |
No examples provided.
search_readiness Search Agent Readiness ~322
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.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | – | Current Sourcey Entity slug or immutable Entity ID. |
| 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). |
| letter | string | – | Exact published letter. |
| limit | integer | – | Maximum results to return; defaults to 10. |
| product | string | – | Exact Agent Readiness product key. |
| query | string | – | Vendor, service, API, product, or job. |
| Name | Type | Req | Description |
|---|---|---|---|
| data | array | yes | – |
| release_id | string | yes | – |
| total | integer | yes | – |
| truncated | boolean | yes | – |

How do I install the Sourcey MCP server?
Sourcey is a hosted endpoint at https://mcp.sourcey.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
