# api_call Make a direct API call to any connected service. For advanced use when you need fine-grained control beyond the execute tool. Agent View of the PolicyLayer registry record for `api_call`. HTML page: https://policylayer.com/tools/io-github-0nork-0nmcp/api-call ## Facts - Tool: `api_call` - Server: 0nmcp (`0nmcp`) — https://policylayer.com/tools/io-github-0nork-0nmcp.md - Install: `npx -y 0nmcp` - Homepage: https://github.com/0nork/0nMCP - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server auth posture: open - 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_call", "arguments": {} } } ``` ## Why api_call is rated High This tool can invoke arbitrary APIs on connected services with user-supplied parameters. While the name alone is neutral, the description 'direct API call' and 'fine-grained control' indicate the ability to trigger external operations whose side effects depend entirely on the API endpoint and arguments provided. This matches Execute category (triggers external operations whose effects depend on arguments). From the tool's own definition: "Tool enables 'direct API call to any connected service' with 'fine-grained control', allowing arbitrary requests to external APIs whose effects are determined by arguments and target service implementation." ## Use case AI agents invoke api_call to trigger actions in 0nmcp. 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 0nmcp: ```json { "version": "1", "default": "deny", "tools": { "api_call": { "limits": [ { "counter": "api_call_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on 0nmcp (217) - `crm_marketplace_delete_charge` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-marketplace-delete-charge.md - `crm_marketplace_uninstall` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-marketplace-uninstall.md - `crm_media_bulk_delete` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-media-bulk-delete.md - `crm_media_delete` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-media-delete.md - `patent_watchlist` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/patent-watchlist.md - `shadcn_theme` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/shadcn-theme.md - `vault_container_revoke` — Destructive — https://policylayer.com/tools/io-github-0nork-0nmcp/vault-container-revoke.md - `ai_chat` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/ai-chat.md - `ai_embed` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/ai-embed.md - `ai_generate` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/ai-generate.md - `app_build` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/app-build.md - `app_open` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/app-open.md - `brain_compile` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/brain-compile.md - `brain_import` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/brain-import.md - `brain_train` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/brain-train.md - `council_debate` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/council-debate.md - `council_solve` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/council-solve.md - `crm_build_ai_workflow` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-build-ai-workflow.md - `crm_deploy_snapshot` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-deploy-snapshot.md - `crm_run_ai_workflow` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/crm-run-ai-workflow.md - `execute` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/execute.md - `flow_run_now` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/flow-run-now.md - `landing_pages_deploy` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/landing-pages-deploy.md - `plugin_build` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/plugin-build.md - `plugin_execute` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/plugin-execute.md - `rc_sequence_to_user_workflow` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/rc-sequence-to-user-workflow.md - `run_workflow` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/run-workflow.md - `site_run` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/site-run.md - `training_feed` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/training-feed.md - `vault_container_escrow_unwrap` — Execute — https://policylayer.com/tools/io-github-0nork-0nmcp/vault-container-escrow-unwrap.md - …and 187 more: https://policylayer.com/tools/io-github-0nork-0nmcp.md ## For agents This record is a snapshot.
