Frequently Asked Questions
How do I connect Langfuse to my app?
Use Weavz Hosted Connect for Custom authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does Langfuse support?
Langfuse supports 4 tools including List Traces, Get Trace, List Generations, Score Trace.
Can I use Langfuse with AI agents?
Yes. Add Langfuse to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect Langfuse to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add Langfuse as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped Langfuse tools exposed by that workspace.
Does Langfuse work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved Langfuse work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with Langfuse?
Langfuse exposes 4 tools, including List Traces, Get Trace, List Generations, Score Trace. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can Langfuse be used in stateful agent workflows?
Yes. Agents can combine Langfuse tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
What authentication does Langfuse use?
Langfuse uses Custom. Weavz stores credentials securely and uses them for authorized action execution.
How much does the Langfuse integration cost?
The Langfuse integration is included on all Weavz plans including the free tier with 20,000 actions per month. No credit card required.
