# get_release_ledger THE tool for "did this piece ship on this channel" — reads the cross-channel Release Ledger, the queryable truth for every confirmed send (x/linkedin/instagram/facebook/threads, hub letters, Beehiiv) written by the publish rail itself at send time. Use this instead of title-matching or a markdown tracking doc when a reconciler or operator asks whether a piece released, where it released, or wants a recent-releases feed. Returns rows plus a per-piece coverage summary (which channels a piece is KNOWN to have shipped on — never a speculative claim about what's missing).

Required for company-scoped tools. | | `piece_key` | string | no | Filter to one piece's releases (e.g. 'output:', 'idea:', 'hub-letter:'). | | `released_by` | string | no | Filter by who released it: 'agent', 'human', or 'system'. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_release_ledger", "arguments": { "companyId": "" } } } ``` ## Why get_release_ledger is rated Low This tool retrieves and queries historical publication data from an immutable ledger written by the publish rail. It performs no side effects—no data creation, modification, deletion, or external execution. The blast radius of misuse is minimal: an agent could retrieve sensitive release timing or metadata, but cannot alter records or trigger actions. Categorized as Read with low severity. From the tool's own definition: "Tool description states it 'reads the cross-channel Release Ledger' and 'Returns rows plus a per-piece coverage summary'. The verbs are query/read operations: 'queryable truth', 'asks whether a piece released', 'wants a recent-releases feed'." Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents call get_release_ledger to retrieve information from Freedom Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Freedom Mcp: ```json { "version": "1", "default": "deny", "tools": { "get_release_ledger": {} } } ``` ## Other tools on Freedom Mcp (237) - `clear_pipeline_learnings` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/clear-pipeline-learnings.md - `deactivate_agent` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/deactivate-agent.md - `delete_icp` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/delete-icp.md - `delete_idea` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/delete-idea.md - `delete_knowledge` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/delete-knowledge.md - `delete_objective` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/delete-objective.md - `remove_agent_activity` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/remove-agent-activity.md - `remove_background` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/remove-background.md - `remove_dashboard_widget` — Destructive — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/remove-dashboard-widget.md - `audit_brand_visibility` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/audit-brand-visibility.md - `browse_url` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/browse-url.md - `challenge_as_customer` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/challenge-as-customer.md - `decide_command_center_item` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/decide-command-center-item.md - `deliberate` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/deliberate.md - `generate_image_xai` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/generate-image-xai.md - `generate_vector_image` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/generate-vector-image.md - `generate_video_veo` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/generate-video-veo.md - `hire_agent` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/hire-agent.md - `hire_agent_with_context` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/hire-agent-with-context.md - `invoke_integration` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/invoke-integration.md - `posthog_hogql` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/posthog-hogql.md - `request_attention_spawn` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/request-attention-spawn.md - `resolve_work` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/resolve-work.md - `run_quality_check` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/run-quality-check.md - `run_tactic` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/run-tactic.md - `send_email` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/send-email.md - `toggle_agent_schedule` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/toggle-agent-schedule.md - `trigger_agent_activity` — Execute — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/trigger-agent-activity.md - `set_meta_ad_status` — Financial — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/set-meta-ad-status.md - `update_meta_ad_budget` — Financial — https://policylayer.com/tools/com-getfreedomos-freedom-mcp/update-meta-ad-budget.md - …and 207 more: https://policylayer.com/tools/com-getfreedomos-freedom-mcp.md ## For agents This record is a snapshot.
