# disable_data_checksums A write tool on the Mcpg MCP server. Agent View of the PolicyLayer registry record for `disable_data_checksums`. HTML page: https://policylayer.com/tools/io-github-devopam-mcpg/disable-data-checksums ## Facts - Tool: `disable_data_checksums` - Server: Mcpg (`pypi:mcpg`) — https://policylayer.com/tools/io-github-devopam-mcpg.md - Install: `npx -y pypi:mcpg` - Homepage: https://github.com/devopam/MCPg - Risk category: Write (Medium 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": "disable_data_checksums", "arguments": {} } } ``` ## Why disable_data_checksums is rated Medium Disabling checksums modifies database configuration reversibly (can be re-enabled), affecting data integrity verification rather than deleting data or executing arbitrary code. This is a Write operation because it changes system state. Severity is medium because disabling checksums could allow undetected data corruption to propagate, but the action itself is reversible and doesn't directly cause data loss. From the tool's own definition: "Tool name 'disable_data_checksums' indicates modification of database integrity settings. No description provided to clarify exact behavior." ## Use case AI agents use disable_data_checksums to create or update resources in Mcpg, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcpg environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcpg: ```json { "version": "1", "default": "deny", "tools": { "disable_data_checksums": { "limits": [ { "counter": "disable_data_checksums_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Mcpg (251) - `cancel_migration` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/cancel-migration.md - `drop_graph` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/drop-graph.md - `drop_property_graph` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/drop-property-graph.md - `drop_publication` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/drop-publication.md - `drop_subscription` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/drop-subscription.md - `dump_database` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/dump-database.md - `partman_drop_partition` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/partman-drop-partition.md - `prune_audit_events` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/prune-audit-events.md - `restore_database` — Destructive — https://policylayer.com/tools/io-github-devopam-mcpg/restore-database.md - `cancel_query` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/cancel-query.md - `cluster_vectors` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/cluster-vectors.md - `complete_migration` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/complete-migration.md - `dry_run_ddl` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/dry-run-ddl.md - `enable_extension` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/enable-extension.md - `enable_logical_replication_on_demand` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/enable-logical-replication-on-demand.md - `enable_redis_fdw` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/enable-redis-fdw.md - `generate_graph_projection` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/generate-graph-projection.md - `generate_test_data` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/generate-test-data.md - `hybrid_search` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/hybrid-search.md - `maintain_turboquant_index` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/maintain-turboquant-index.md - `mmr_search` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/mmr-search.md - `open_cursor` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/open-cursor.md - `optimize_query` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/optimize-query.md - `partman_run_maintenance` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/partman-run-maintenance.md - `pg_search_run` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/pg-search-run.md - `prepare_migration` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/prepare-migration.md - `prewarm_recommended` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/prewarm-recommended.md - `prewarm_relation` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/prewarm-relation.md - `recommend_redistribute` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/recommend-redistribute.md - `reindex_pg_search_index` — Execute — https://policylayer.com/tools/io-github-devopam-mcpg/reindex-pg-search-index.md - …and 221 more: https://policylayer.com/tools/io-github-devopam-mcpg.md ## For agents This record is a snapshot.
