pipeline_delete
Permanently delete a pipeline definition, its versions, and its draft while retaining governed audit history. The client must obtain confirmation and pass confirm=true.
When to use it
Use pipeline_delete to delete a pipeline. On the workspace endpoint, pass projectId from project_list. On a project-scoped endpoint, the project is already bound: omit that argument and use the schema discovered from that endpoint.
Arguments
| Name | Type | Required | Default | Constraints |
|---|---|---|---|---|
id | string | Yes | — | Format: uuid; Pattern constraint; see full schema |
confirm | boolean | Yes | — | Must equal true |
idempotencyKey | string | Yes | — | Minimum length: 8; Maximum length: 200 |
projectId | string | Yes | — | Format: uuid; Pattern constraint; see full schema |
View the complete input schema, including nested contracts and alternative shapes. The schema is extracted from the workspace server’s Zod definitions. Runtime validation also enforces custom checks that JSON Schema cannot express.
Response shape
The operation-specific payload is returned in data; its contents follow the operation described above.
MCP returns a text block containing the JSON operation result and a
structuredContent copy. The envelope includes data, completeness,
truncated, freshness, and warnings. Depending on the operation it can also
include nextCursor, evidence, job, or receipt.
Check those fields before treating a conversational summary as the result.
When a job is returned, inspect its status with the appropriate execution tool;
a queued response is not confirmation that work finished. Follow evidence links
when checking the underlying records.
Input methods
This request illustrates the argument structure. Replace every angle-bracket placeholder with a real value and supply any applicable optional fields from the schema. Nested business contracts must match your actual configuration. Send it through an authenticated, initialized MCP client; this JSON alone does not establish a session or sign you in.
Use Semogram’s pipeline_delete tool to delete a pipeline. Inspect the required inputs and target first, then show me what will change before executing it.
Choose the project explicitly before making this request. Use real resource IDs returned by earlier reads; a resource name is not a UUID. Do not fill missing business inputs with invented values.
This is an MCP tools/call request, not a form to paste into Semogram. Send it through an authenticated, initialized MCP client.

}FAQ
What access and approvals are required?
Required permission scopes: pipelines:write.
OAuth uses current workspace membership; API keys use their assigned scopes
and grants. Discovery can exclude tools the caller cannot use.
Read-only annotation: No. Destructive annotation: Yes.
The schema requires confirm: true. Ask the user to review the exact target and approve the operation before calling it.
How should I handle retries?
The server marks this operation as idempotent. When an idempotencyKey is accepted, keep the same key only for a retry of the exact same input; use a new key for new work. For 429 responses, honor Retry-After rather than retrying immediately.
Why is this tool missing or returning an error?
Confirm the workspace, resource IDs, and permission scopes. Read the returned error before changing the request. See connection, authentication and troubleshooting for sign-in, scope, resource access, and rate-limit errors.
project_delete
Permanently delete the selected project and its governed contents after active-work checks. The client must obtain confirmation and pass confirm=true. The MCP endpoint stops existing after success.
pipeline_schedule_delete
Permanently remove a pipeline schedule. Existing retained runs are unchanged. The client must obtain confirmation and pass confirm=true.
