# anthropic_create_message Send a message to the Anthropic Messages API (Claude models). Useful for agents that need to call Claude programmatically or compare model outputs. Agent View of the PolicyLayer registry record for `anthropic_create_message`. HTML page: https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/anthropic-create-message ## Facts - Tool: `anthropic_create_message` - Server: UnClick (`@unclick/mcp-server`) — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server.md - Install: `npx -y @unclick/mcp-server` - Homepage: https://github.com/malamutemayhem/unclick-agent-native-endpoints.git - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 10 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `model` | string | no | Claude model ID (default: claude-sonnet-4-6) | | `top_k` | number | no | | | `top_p` | number | no | | | `prompt` | string | no | Convenience: single user message (alternative to messages array) | | `system` | string | no | System prompt | | `api_key` | string | yes | | | `messages` | object | no | Array of {role, content} message objects | | `max_tokens` | number | no | Max tokens to generate (default: 1024) | | `temperature` | number | no | | | `stop_sequences` | object | no | Array of stop sequences | 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": "anthropic_create_message", "arguments": { "api_key": "" } } } ``` ## Why anthropic_create_message is rated High This tool triggers an external API call to Anthropic's Claude models, executing LLM inference with arbitrary inputs. It spans Execute territory because it runs an external operation whose effects depend on the arguments passed. From the tool's own definition: "'Send a message to the Anthropic Messages API' and 'agents that need to call Claude programmatically'" Risk signals: Handles credentials or secrets (api_key) · High parameter count (10 properties) ## Use case AI agents invoke anthropic_create_message to trigger actions in UnClick. 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 UnClick: ```json { "version": "1", "default": "deny", "tools": { "anthropic_create_message": { "limits": [ { "counter": "anthropic_create_message_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on UnClick (1661) - `delete_todo` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/delete-todo.md - `email_delete` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/email-delete.md - `file_sync_prune` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/file-sync-prune.md - `pinecone_delete_vectors` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/pinecone-delete-vectors.md - `telegram_manage_chat` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/telegram-manage-chat.md - `upstash_redis_del` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/upstash-redis-del.md - `vault_action` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/vault-action.md - `vercel_delete_env` — Destructive — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/vercel-delete-env.md - `ackermann` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/ackermann.md - `avl_tree` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/avl-tree.md - `baby_giant_step` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/baby-giant-step.md - `bellman_ford` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bellman-ford.md - `bezier_curve` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bezier-curve.md - `bitmask_ops` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bitmask-ops.md - `bitwise_calc` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bitwise-calc.md - `bloom_filter` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bloom-filter.md - `bluesky_action` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/bluesky-action.md - `burrows_wheeler` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/burrows-wheeler.md - `cartesian_tree` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/cartesian-tree.md - `chromatic_number` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/chromatic-number.md - `circleci_trigger_pipeline` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/circleci-trigger-pipeline.md - `cohere_chat` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/cohere-chat.md - `cohere_classify` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/cohere-classify.md - `cohere_generate` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/cohere-generate.md - `commonsensepass_check` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/commonsensepass-check.md - `complex_calc` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/complex-calc.md - `compliancepass_run` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/compliancepass-run.md - `convex_hull_3d` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/convex-hull-3d.md - `convolution` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/convolution.md - `copypass_run` — Execute — https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server/copypass-run.md - …and 1631 more: https://policylayer.com/tools/io-github-malamutemayhem-unclick-mcp-server.md ## For agents This record is a snapshot.
