You connect Claude Code to your logs over MCP, the Model Context Protocol. Once your log backend exposes an MCP server and you register it with Claude Code, you ask about your logs in plain language from your editor, with no dashboard and no query syntax. Here is how to set it up.
What MCP is
MCP, the Model Context Protocol, is like an API, but a protocol built specifically for AI agents. It is what lets a client like Claude Code connect to external tools and data, including your logs.1
Why query your logs from Claude Code
It is much faster than digging through logs by hand. Instead of opening multiple dashboards and tracing through requests yourself, you ask, and the answer comes back to you.
Claude Code also already has access to your codebase, so it can validate a failing log against the code that produced it, not just surface the line.
How to connect Claude Code to your logs
1. Get your logs into a backend that speaks MCP
Your logs need to live somewhere that exposes an MCP server. We recommend Fixter: your logs live in Fixter and it exposes an MCP server out of the box, so there is nothing to wire up yourself. If you already run another backend, check whether it offers an MCP server, or migrate to Fixter.
2. Register the MCP server with Claude Code
Add the server with claude mcp add, using the HTTP transport and your backend's MCP URL, with your token in an authorization header:2
Replace the URL and token with the ones from your Fixter project (or your own backend's MCP server).
3. Ask in plain language
That is it. From the same session you code in, ask about your logs and Claude Code calls the MCP server to answer.
What you can ask once it is connected
The questions look like the ones you would ask a teammate with the logs open: what is erroring most in the last hour, why the checkout endpoint got slow, every log for one user's failed request, whether anything broke right after the last deploy.
Key takeaways
- MCP is the open standard that lets Claude Code reach external data, including your logs
- Get your logs into a backend that exposes an MCP server (Fixter does this out of the box)
- Register it with claude mcp add, or commit a .mcp.json to share it with the team
- Then ask in plain language; it is faster than digging by hand, and Claude Code can tie the log to your code
Frequently asked questions
What is MCP?
MCP, the Model Context Protocol, is an open standard that lets a client like Claude Code connect to external tools and data sources. A tool exposes an MCP server, and any MCP-compatible client can use it. It is the layer that lets Claude Code reach your logs.
How do I connect Claude Code to my logs?
Get your logs into a backend that exposes an MCP server, then register that server with Claude Code using the claude mcp add command (or a committed .mcp.json file). Once it is registered, you ask about your logs in plain language and Claude Code queries them through the MCP server.
Can Claude Code read my production logs?
Yes, once you register a log MCP server. Claude Code has no access to your logs by default; you grant it by adding the server. From then on it can query those logs in response to your questions, scoped to whatever the server exposes.
Why is this better than a log dashboard?
It is faster, and it understands more. You skip the dashboard and query syntax and just ask in the editor you already work in, and because Claude Code also has your codebase, it can tie a failing log line back to the code that produced it.
