# add_comment Add the given text as a new comment to the given card Agent View of the PolicyLayer registry record for `add_comment`. HTML page: https://policylayer.com/tools/io-github-delorenj-mcp-server-trello/add-comment ## Facts - Tool: `add_comment` - Server: Trello (`@delorenj/mcp-server-trello`) — https://policylayer.com/tools/io-github-delorenj-mcp-server-trello.md - Install: `npx -y @delorenj/mcp-server-trello` - Homepage: https://github.com/delorenj/mcp-server-trello - 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": "add_comment", "arguments": {} } } ``` ## Why add_comment is rated Medium This tool creates new data (a comment) on a Trello card in a reversible manner. Comments can typically be edited or deleted later, making this a Write operation rather than Destructive. The severity is medium because while comment injection could spam or mislead users, it does not delete data, move money, or execute arbitrary code. From the tool's own definition: "Tool name: add_comment. Description: 'Add the given text as a new comment to the given card.' The verb 'add' and the action of creating a new comment indicate data creation." ## Use case AI agents use add_comment to create or update resources in Trello, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trello environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
