Pulse MCP

MCP server for Pulse — the open compute-pricing reference. Daily GPU and inference-token medians, free under CC-BY 4.0.

The server is hosted at https://pulsebenchmarks.com/mcp. This repository is a public mirror of the production handler, kept here so MCP registries and end users have a stable source URL.

What you can do with it

Install the server in Claude Desktop, Cursor, Cline, or any MCP-aware client. You get five tools that wrap the public Pulse API and return JSON with pre-formatted citations:

• list_indices — every published index with current value, freshness, and methodology version
• get_series — full payload for one index: history, per-provider observations, contributing-provider list
• latest_value — quick lookup for one index, with cite_as string ready to paste
• get_status — pipeline freshness and per-provider collection health
• compare_indices — current values across multiple indices side-by-side

The data covers four GPU series (H100 SXM and A100 80GB, hyperscaler vs neocloud), four additional neocloud series (B200, H200 141GB, H100 PCIe, A100 80GB spot), and an inference-token basket anchored on Llama 3.3 70B FP8.

Install

The server is hosted, so the install is the same on every client: point mcp-remote at the public endpoint.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on Windows/Linux:

{
  "mcpServers": {
    "pulse": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://pulsebenchmarks.com/mcp"]
    }
  }
}

Restart Claude Desktop. You should see pulse in the tools menu.

Cursor

Add to ~/.cursor/mcp.json (or use the in-app MCP settings). Same JSON as above; full file in examples/cursor_mcp.json.

Cline / other clients

Any MCP client that speaks mcp-remote over HTTP works the same way. The endpoint is https://pulsebenchmarks.com/mcp; transport is JSON-RPC 2.0 over POST; no auth.

Tools

Tool	Description
list_indices	List every published Pulse compute-pricing index with its current value, freshness, methodology version, and status.
get_series	Fetch the full payload for one Pulse index: metadata, gated daily headline series, per-provider observations, contributing-provider list. Optional range filter (30d / 90d / 1y / all).
latest_value	Quick lookup: the latest published value for one index, with minimal payload and a ready-to-paste cite_as string.
get_status	Pipeline freshness and per-provider collection health.
compare_indices	Compare current values across multiple Pulse indices (e.g. hyperscaler vs neocloud for the same GPU).

Full input schemas and tool implementations are in functions/mcp.js.

Data and methodology

The MCP server is a thin wrapper over Pulse's public HTTP endpoints. The same data is available without an MCP client:

• Methodology: https://pulsebenchmarks.com/methodology/
• Public API: GET https://pulsebenchmarks.com/api/indices, GET https://pulsebenchmarks.com/api/indices/{slug}, GET https://pulsebenchmarks.com/api/status
• Bulk export (CC-BY 4.0): https://pulsebenchmarks.com/data/data_export.json
• Reproducibility script: https://pulsebenchmarks.com/methodology/#reproducibility
• Agent guide: https://pulsebenchmarks.com/llms.txt

Methodology v1.0 covers four headline GPU series (H100 SXM and A100 80GB, hyperscaler vs neocloud) plus a Llama 3.3 70B FP8 inference-token basket. Series additions and methodology changes are versioned and documented in the methodology changelog.

Self-host

The handler is a single Cloudflare Pages Function: functions/mcp.js. It has no dependencies, no build step, and no environment variables. To deploy your own:

1. Drop functions/mcp.js into a Cloudflare Pages project (or adapt to Workers — onRequest maps to fetch with minor changes).
2. The handler issues same-origin sub-requests to /api/indices, /api/indices/{slug}, and /api/status — point those at the public Pulse endpoints, or proxy them through your own deployment.
3. Hit GET /mcp to confirm the discovery payload returns; hit POST /mcp with an initialize JSON-RPC envelope to confirm the protocol layer.

For most users we recommend the hosted server. Self-hosting is mainly useful if you want to add caching, vendor it into a private network, or extend the tool set against the same public endpoints.

The production handler lives in the main Pulse codebase; changes there flow into this repository on a release cadence. PRs are reviewed as time allows; for fast turnaround on data or tool-shape changes, open an issue first so we can align before you write code.
