How do I install Langfuse?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Langfuse need an API key?

The publisher lists these environment variables: LANGFUSE_SECRET_KEY, LANGFUSE_PUBLIC_KEY, LANGFUSE_BASE_URL.

What transport does Langfuse use?

Langfuse runs locally over stdio.

When was Langfuse last checked?

Last checked 2026-11-08. MCP server for Langfuse LLM observability — trace and observation analysis.

PulseMCP's MCP Servers

We build reliable servers thoughtfully designed for MCP Client-powered workflows.

Design principles

You can have confidence that any Pulse-branded MCP server was built with these north stars in mind:

Purpose-built. LLM-powered MCP clients offer uniquely new user interaction patterns that necessitate a different layer of abstraction than the REST API's from a pre-AI era. We thoughtfully scope drawing lines like building a new server, versus incorporating a new feature in another server. Or deciding where one slew of REST API endpoints might be better packaged as a single Tool call. And more.

Easy set up. Many MCP servers die before ever getting a chance to be used. We offer guides and a frustration-free experience to get going with our MCP servers inside your favorite MCP clients.

Time savings. By minimizing the number of tool chain steps or conversational turns you need to accomplish a task, our MCP servers will save you (and your agents) time waiting for a task to be completed.

Inference cost savings. By minimizing the number of tokens you need to consume to a accomplish a task, our MCP servers will save you on your LLM inference bills.

Reliability. You should have confidence that you can deploy our servers in a production application serving mass market consumers or business clients.

Future-proof. We sit on the bleeding edge of the MCP specification, working to push the ecosystem forward. As such, you can be sure that if you commit to baking our server into your workflow, it will self-improve over time to take advantage of the latest and greatest MCP features.

Productionized Servers

These are PulseMCP-branded servers that we intend to maintain indefinitely as our own offerings.

The MCP Registry column controls whether the server is published to the official MCP Registry (com.pulsemcp/<server-name>) by the publish-mcp-registry.yml workflow.

Name	Description	Local Status	Remote Status	MCP Registry	Target Audience	Notes
pulse-fetch	Pull internet resources into context	0.3.3	Not Started	Yes	Agent-building frameworks (e.g. fast-agent, Mastra, PydanticAI) and MCP clients without built-in fetch	Supports Firecrawl and BrightData integrations; HTML noise stripping; Resource caching; LLM extraction
pulse-subregistry	Browse the PulseMCP Sub-Registry	0.0.8	Not Started	Yes	Developers discovering MCP servers from the PulseMCP Sub-Registry	Search and pagination; Version selection; Integrates with PulseMCP Sub-Registry API
image-diff	Programmatic image comparison	0.1.3	Not Started	Yes	Developers comparing design mocks against UI implementations	Pixel-level diff with clustering; Heatmap visualization; Anti-aliasing detection; Auto-alignment for different-sized images
svg-tracer	Bitmap-to-SVG vector tracing	0.1.3	Not Started	Yes	Developers converting bitmap images to SVG vector graphics	Supports PNG, JPG, WebP, BMP, GIF, TIFF; Alpha channel preprocessing; Target size scaling; Customizable tracing parameters

Experimental Servers

These are high-quality servers that we may discontinue if the official provider creates and maintains a better MCP server.
