execute_v2_source_program

Executes a staged-source step using the function's typed arguments. A preview returns reviewed set/clear counts and a token; publication is a separate operation. Source begin uses a key inside program.arguments. Chunk identity and digest protect append and seal retries.

These signatures come from local MCP tool discovery. Use the signature registered by your deployment and confirm your identity and permissions before calling the tool.

Endpoint signatures and example arguments

Examples show the arguments to the tool. Replace placeholder IDs and illustrative revisions with values from your authorized disposable scope.

Handling errors

MCP_TOOL_CAPACITY_NOT_DISPATCHED means the server did not dispatch this call. MCP_TOOL_DEADLINE_OUTCOME_UNKNOWN or MCP_TOOL_PROCESS_FAILED_OUTCOME_UNKNOWN leaves the outcome unknown. For a call with effects, reconcile the original request before starting a new one. For a scoped denial, verify the caller's grant and the selected target.
