AI agents invoke mistral_chat_completion 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
model | string | — | Model ID (default: mistral-small-latest) |
top_p | number | — | |
prompt | string | — | Single user message (alternative to messages) |
api_key | string | — | Mistral API key |
messages | string | — | JSON array of {role, content} messages |
max_tokens | number | — | |
temperature | number | — | |
system_prompt | string | — |
Parameters from the server's own tool schema.
This is an Execute category tool because it triggers execution of external code/operations (a remote AI model inference) whose side effects and output depend entirely on the arguments provided. It is not Read (it does not merely retrieve data), Write (it does not persist data), Destructive (it does not delete/overwrite), Financial (no money moves), or Other.
From the tool's definition The tool description explicitly states 'Run a chat completion with a Mistral AI model', indicating execution of an external AI service with model-dependent behavior.

Attacks that exploit this kind of access
Run a chat completion with a Mistral AI model (mistral-small, mistral-medium, mistral-large, etc.). It is categorised as a Execute tool in the UnClick MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
mistral_chat_completion accepts 8 parameters: model, top_p, prompt, api_key, messages, max_tokens, temperature, system_prompt. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for mistral_chat_completion: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches UnClick. Nothing to install.
mistral_chat_completion is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the mistral_chat_completion rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mistral_chat_completion. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mistral_chat_completion is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
