Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Read CATS candidates, jobs and pipelines, and make explicitly confirmed recruiting changes.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with cats_upgrade (it returns a Stripe Checkout link). Cancel any time with cats_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running cats_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Create a v3 API key in CATS under Administration → API Keys. Legacy Transaction Codes do not work. The generation form offers no read-only scope selector. Authorize UsefulAPI and your selected AI client to process only data you are entitled to share. CATS account eligibility and vendor charges remain separate from UsefulAPI plans. This independent connector makes no claim of vendor approval or endorsement.
Candidate/contact records contain personal information. Do not use this workflow for government IDs, health data, personal financial information or other CATS Prohibited Data. Known credential and sensitive financial/health fields and HAL link blocks are filtered; customers must still review free text and custom fields. Tool results reach your chosen AI client and LLM provider, whose privacy and retention policies also apply. Revoke the API key in CATS to stop vendor access; disconnect UsefulAPI to end this connection.
CATS documents a rolling 500 API requests/hour limit; its counter scope is not specified. Collection pages default to 25, maximum 100. Authentication is capped at 10 seconds/64 KiB; operation replies at 30 seconds/8 MiB. Billing follows the verified CATS site ID, so rotation of a key within the same site keeps the account identity.
All four writes require confirm:true: create a candidate, log candidate activity, create a task or change pipeline status. Assigned tasks may notify a user. No email/SMS-send request is made by an activity note, even when its activity type is email or text_message. Independently configured account automation and webhooks can still react to changes.
Pipeline moves read the workflow/status metadata, explicitly request every returned trigger be suppressed with fire:false, and send create_activity=false. An already-current status makes no write. Preflight reads are not an atomic lock, so concurrent changes remain possible; independent webhooks are not suppressed. No email delivery, delete, attachment download, bulk-export endpoint or webhook-management tool is exposed.
No vendor request is automatically replayed. Creates require the documented 201 and a matching Location record ID; inconsistent or uncertain acknowledgements are errors. Inspect CATS before retrying a write. Date-only task/activity dates are sent at midnight UTC.
The 34 vendor tools were checked against the current API reference and local mocks. Actual own-trial reads verified account identity and HAL response structures, including vendor-supplied sample records. No real customer recruiting records or business writes were tested. Current terms allow customer-directed third-party software, and the vendor publishes external API-key setup guidance; this does not assert CATS reviewed UsefulAPI.
