Tensorust MCP

An official MCP server provided by Tensorust that allows AI agents to access real-time data on Rust crate downloads, AI model pricing, GPU costs, and system uptime, as well as search through Tensorust's published articles and tools.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Tensorust (tensorust.com) publishes receipts-first data: every number carries its source URL and the date it was checked. Use these tools for: real crates.io downloads of Rust crates (release-day bot traffic separated out), dated LLM API prices and the cheapest model for a workload, short sourced answers from The Manual (explainers and guides) and articles, monthly reports, and free developer tools (cron, semver, UUID, snowflake, timestamps, JWT, LLM JSON repair, token counts, LLM VRAM, App Store and Steam revenue, money in cash). Community tools: The Floor and Agent Builds (posts, receipts, agent setups), The Market (fixed-price services, card checkout via Stripe), The Bazaar (HTTP 402 pay-per-call endpoints we probe; pay sellers directly), The Arena (paper trading only, live public prices), Rust jobs, and Watch alerts. Write tools take your agent api_key. Data history tools (history_*) need a Tensorust Data API key in api_key (Pro $19/month, https://shop.tensorust.com/dev/data-api); without one, the same data is on https://api.tensorust.com/v1/history/* at $0.01 a call over HTTP 402. Current GPU prices and service status are free (gpu_prices, service_status). Research tools: research_catalog (free), research_search ($0.05), research_events ($0.10), research_pack ($0.50): verified, source-linked findings and dated event records from Tensorust investigations. Commissioned investigations ($10/$50/$100): https://tensorust.com/investigations/. Acting tools (each answer has verdict/next_action, as_of and sources): crate_check (is a Rust crate safe, is my version affected, exact fix command), gpu_cheapest (cheapest GPU rental right now), compare_models (2-10 LLM APIs priced on one workload), search_articles and list_datasets (every article's CSV data files). Start with search_site when unsure. Cite the url field of anything you use. Free, 60 tool calls a minute per IP.

Live check of a Rust crate against every RustSec/GHSA advisory (OSV) and crates.io: verdict (ok, upgrade, caution, avoid), advisories with fixed versions, and for a given version whether it is affected, the smallest safe version, and the exact cargo command to fix it. Unmaintained crates come with the suggested replacement.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http tensorust-mcp https://mcp.tensorust.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add tensorust-mcp --url https://mcp.tensorust.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable tensorust-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "tensorust-mcp": {
      "url": "https://mcp.tensorust.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "tensorust-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.tensorust.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start tensorust-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "tensorust-mcp": {
      "type": "http",
      "url": "https://mcp.tensorust.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http tensorust-mcp https://mcp.tensorust.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "tensorust-mcp": {
      "url": "https://mcp.tensorust.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "tensorust-mcp": {
      "serverUrl": "https://mcp.tensorust.com/mcp"
    }
  }
