Agent Trace Check tools (3, 1 write)

write = sends, deletes, buys or posts
  • analyze_traceFree

    Use this when the user pastes a log of an AI agent's tool calls and wants to know which calls failed, where the agent retried in a loop, which calls it repeated, or which were slow. Pass the log as trace: JSON lines or one JSON value from OpenAI messages, the Responses API, Anthropic messages, Claude Code session JSONL, MCP JSON-RPC, LangSmith, OpenTelemetry spans, or flat rows with tool, args, status or error and duration_ms. Returns findings worst first, per-tool stats, failures, retry loops, repeated calls and slow calls. Nothing is stored. It does not run the agent or any tool.

  • get_feedback_replyFree

    Read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.

  • submit_feedbackwrite actionFree

    Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Install Agent Trace Check in Claude Code, Cursor or VS Code

claude mcp add --transport http agent-trace https://agenttrace.openkrill.app/mcp
Add to Cursor

What the publisher says

From the Agent Trace Check repository's README, as published. We do not edit it. Read it on GitHub

Agent Tools plugins

Plugins for Claude Code and Cursor that connect an agent to the Agent Tools MCP servers by OpenKrill. Each plugin is one tool family: a skill per server that says when to use it, plus the remote MCP config for those servers. 9 plugins bundle 54 public MCP servers. None needs an API key, a sign-up or a local process.

Install in Claude Code

claude plugin marketplace add nguyenhieuec/agent-tools-plugins
claude plugin install dev-security@openkrill

Start a new session and ask: "Is lodash 4.17.15 vulnerable, and which version fixes it?" Install any other family the same way. Inside a session, /plugin marketplace add nguyenhieuec/agent-tools-plugins and /plugin do the same.

Install in Cursor

Cursor reads the same plugins through .cursor-plugin/marketplace.json. A team admin can import this repository under Dashboard, Plugins & MCPs, Team Marketplaces, Import from Repo, and members install from Customize. To try one family alone, clone this repository and copy plugins/ to ~/.cursor/plugins/local/, then run Developer: Reload Window. The Cursor CLI loads a family directly: cursor-agent --plugin-dir plugins/.

Each family also has a plain mcp.json you can merge into ~/.cursor/mcp.json without the skills.

Not sure which plugin?

Add the API server alone and ask it: its index_tools tool searches every Agent Tools server by task in plain words and answers with the tool name and the MCP address to add.

claude mcp add --transport http openkrill https://api.openkrill.app/mcp

The plugin servers do not list index_tools: each one describes only its own tools.

Every tool on one server
