# api_prepare_request Prepare a saved request or partial draft; resolve environment, runtime variables and overrides without sending. Returns a fixed redacted preview and preparedId. No scripts are run. Secrets remain host-side. Optional extractions bind response values into host-side runtime variables so later requests can use {{name}}; extracted values are never returned to the model. request.cases replaces the whole named test-case list for this request: cases you add are stamped as agent-authored and must be reviewed by a human before they count as acceptance evidence, and cases a human created cannot be modified or deleted (the host rejects that with API_WORKBENCH_USER_CASE_PROTECTED). caseId runs one existing case with its own assertions. useCookieJar defaults to off and only touches host-side in-memory cookies for this project; cookie values never come back to you. To upload local files, set body.kind to multipart and list body.files as {id, name (form field), path} entries: the host resolves realpath and file size, shows every path on the approval card, and only reads the bytes after the human approves the send; the saved request keeps file references only, so a later session must re-declare paths. Directories, devices, FIFOs, dangling links and files over 20 MiB are rejected, and a file changed after preparation is rejected instead of being uploaded. Prepare a new identity only for an intentional new network request. Agent View of the PolicyLayer registry record for `api_prepare_request`. HTML page: https://policylayer.com/tools/dutydeck/api-prepare-request ## Facts - Tool: `api_prepare_request` - Server: DutyDeck (`taokoplay/DutyDeck`) — https://policylayer.com/tools/dutydeck.md - Homepage: https://github.com/taokoplay/DutyDeck - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "api_prepare_request", "arguments": {} } } ``` ## Why api_prepare_request is rated High api_prepare_request triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up. Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents invoke api_prepare_request to trigger actions in DutyDeck. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches DutyDeck: ```json { "version": "1", "default": "deny", "tools": { "api_prepare_request": { "limits": [ { "counter": "api_prepare_request_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on DutyDeck (246) - `canvas_cancel_media_run` — Destructive — https://policylayer.com/tools/dutydeck/canvas-cancel-media-run.md - `factory_cancel_experiment` — Destructive — https://policylayer.com/tools/dutydeck/factory-cancel-experiment.md - `mcp__automation__delete_automation` — Destructive — https://policylayer.com/tools/dutydeck/mcp--automation--delete-automation.md - `mcp__planning__delete_calendar_event` — Destructive — https://policylayer.com/tools/dutydeck/mcp--planning--delete-calendar-event.md - `mcp__planning__delete_group` — Destructive — https://policylayer.com/tools/dutydeck/mcp--planning--delete-group.md - `mcp__planning__delete_reminder` — Destructive — https://policylayer.com/tools/dutydeck/mcp--planning--delete-reminder.md - `mcp__planning__delete_tag` — Destructive — https://policylayer.com/tools/dutydeck/mcp--planning--delete-tag.md - `mcp__planning__delete_todo` — Destructive — https://policylayer.com/tools/dutydeck/mcp--planning--delete-todo.md - `media_cancel_generation` — Destructive — https://policylayer.com/tools/dutydeck/media-cancel-generation.md - `media_cancel_run` — Destructive — https://policylayer.com/tools/dutydeck/media-cancel-run.md - `api_run_scenario` — Execute — https://policylayer.com/tools/dutydeck/api-run-scenario.md - `BrowserExecuteJavaScript` — Execute — https://policylayer.com/tools/dutydeck/browserexecutejavascript.md - `BrowserNavigate` — Execute — https://policylayer.com/tools/dutydeck/browsernavigate.md - `BrowserNewTab` — Execute — https://policylayer.com/tools/dutydeck/browsernewtab.md - `BrowserWaitFor` — Execute — https://policylayer.com/tools/dutydeck/browserwaitfor.md - `canvas_run_agent` — Execute — https://policylayer.com/tools/dutydeck/canvas-run-agent.md - `canvas_run_nodes` — Execute — https://policylayer.com/tools/dutydeck/canvas-run-nodes.md - `canvas_run_workflow` — Execute — https://policylayer.com/tools/dutydeck/canvas-run-workflow.md - `canvas_task` — Execute — https://policylayer.com/tools/dutydeck/canvas-task.md - `factory_advance_experiment` — Execute — https://policylayer.com/tools/dutydeck/factory-advance-experiment.md - `factory_diagnose_run` — Execute — https://policylayer.com/tools/dutydeck/factory-diagnose-run.md - `factory_retry_review` — Execute — https://policylayer.com/tools/dutydeck/factory-retry-review.md - `factory_run_batch` — Execute — https://policylayer.com/tools/dutydeck/factory-run-batch.md - `factory_run_scene` — Execute — https://policylayer.com/tools/dutydeck/factory-run-scene.md - `factory_run_step` — Execute — https://policylayer.com/tools/dutydeck/factory-run-step.md - `mcp__automation__run_automation_now` — Execute — https://policylayer.com/tools/dutydeck/mcp--automation--run-automation-now.md - `mcp__collaboration__stop_delegation` — Execute — https://policylayer.com/tools/dutydeck/mcp--collaboration--stop-delegation.md - `mcp__collaboration__stop_delegations` — Execute — https://policylayer.com/tools/dutydeck/mcp--collaboration--stop-delegations.md - `mcp__collaboration__wait_for_delegations` — Execute — https://policylayer.com/tools/dutydeck/mcp--collaboration--wait-for-delegations.md - `media_execute_generation` — Execute — https://policylayer.com/tools/dutydeck/media-execute-generation.md - …and 216 more: https://policylayer.com/tools/dutydeck.md ## For agents This record is a snapshot.
