Real, already-built ATS MCP Servers — give your AI agent access to every ATS platform Knit supports.
Each ATS platform exposes its own API, auth, and schema. A Knit MCP Server wraps that platform's real actions as AI-ready tools your agent can call directly — actions like Add Attachment to ATS Application, Add Tag to Candidate in ATS, Create a Note for a Candidate work the same way no matter which platform your agent is connected to, while Knit manages hosting, auth, and tool exposure underneath.
Every action below is real and already live — not a roadmap item. Browse the full API reference →
This API endpoint allows users to add an attachment to an ATS application. The request requires headers specifying the content type and accept type as 'application/json'. The body of the request must include the applicationId, jobId, candidateId, fileName, and fileType. Optional fields include fileContent, fileUrl, and contentType. The response will indicate success and provide the ID and download URL of the uploaded attachment if successful. If unsuccessful, an error message and type will be provided.
This API endpoint allows adding a tag to a candidate in an ATS (Applicant Tracking System). The request requires the candidate ID, tag text, tag ID, application ID, and job ID. Tags can be added at the application level or candidate level depending on the ATS system. If the tag ID is not available, a dummy ID can be used. The response indicates whether the operation was successful or not.
This API endpoint allows the creation of a note for a candidate. The note may be tied to an application or exist as a global note depending on the ATS (Applicant Tracking System) behavior. The request requires headers specifying 'accept' and 'content-type' as 'application/json'. The request body must include 'candidateId', 'applicationId', and 'note'. The response will indicate success or provide an error message if the operation fails. Supported ATS include Greenhouse, Lever, SAP SuccessFactors, Workable, TeamTailor, Bullhorn, Ashby, SmartRecruiters, Breezy, Zoho Recruit, BambooHR ATS, JazzHR ATS, Recruitee, Oracle Taleo, and Pinpoint.
This API endpoint allows the creation of an application in an ATS (Applicant Tracking System). The request can either include a candidateId for an existing candidate or a candidate object with details such as firstName, lastName, emails, and phones. The jobId and initialStageId are required fields. The response includes the success status and the IDs of the created application, job, and candidate. If the request fails, an error message is provided.
The Get Candidate Tags API retrieves tags associated with a candidate for a specific application and job. It requires three query parameters: candidateId, applicationId, and jobId, all of which are mandatory. The response includes a success flag and a data object containing an array of tags, each with an id and text. If the request fails, an error message is provided.
This API endpoint retrieves a list of global tags from various Applicant Tracking Systems (ATS) such as Greenhouse, Lever, Workday, SAP SuccessFactors, Ashby, Zoho Recruit, JazzHR ATS, and Recruitee. The request requires an 'accept' header specifying 'application/json'. The response includes a success flag and a data object containing an array of tags, each with an 'id' and 'text'. If the request fails, an error object with a message is returned.
This API retrieves a list of rejection reasons from various Applicant Tracking Systems (ATS) such as Greenhouse, Lever, SmartRecruiters, TeamTailor, Breezy, Ashby, Zoho Recruit, Recruitee, and Oracle Taleo. The request requires an 'accept' header specifying 'application/json'. The response includes a success flag and an array of rejection reasons, each with a unique 'id' and 'text' description. In case of an error, an error message is provided.
This API is used to reject an application for a job. It requires the application ID, job ID, candidate ID, rejection ID, and a note as input. The rejection ID should be obtained from the List Rejection Reasons API. The response indicates whether the operation was successful or not. If not successful, an error message is provided.
The Update Application Stage API allows users to update the stage of an application for a candidate in various supported applications such as Greenhouse, Lever, Oracle Cloud HCM, and others. The API requires a POST request with headers specifying 'accept' and 'content-type' as 'application/json'. The request body must include 'applicationId', 'toStageId', 'currentStageId', 'candidateId', and 'jobId' as required fields, with an optional 'subStageId'. The response will indicate success or provide an error message and type if unsuccessful.

26 ATS platforms today — including ADP Workforce Now ATS, Ashby ATS, BambooHR ATS and more. Missing one you need? Knit's AI-assisted connector-build process typically adds a new one within days.
Yes. Every action can both read and write, so your agent can pull ATS data and push updates back to the source app, not just query it.
Knit manages OAuth, credential storage, and refresh for every ATS platform — your team never wrestles with tokens, and there's nothing to configure per platform.
Typically days, not months — the same AI-based connector-build tooling that lets us maintain the 26 ATS mcp servers already live.
No. Knit acts as a stateless passthrough — data is processed on our application server and returned directly to your agent, without being stored on Knit's servers.
You choose the model that fits your business — pricing based on integrated accounts, or based on API call volume. Every plan includes a 30-day free trial before billing starts.
