ProvenTools MCP server

Beta local stdio MCP access to the ProvenTools curated idea library, stored evidence, build prompts, credit balances, and existing validation reports. The package uses Node.js built-ins only and does not host a remote MCP endpoint.

Requirements

• Node.js 22.14 or newer
• A ProvenTools Library account with Live access
• An API key from https://www.proventools.net/dashboard/api-keys

Run proventools login once to save the key in the private ProvenTools CLI config. The MCP server reuses that file and prefers PROVENTOOLS_API_KEY when your MCP client provides it through a secret store or inherited environment. Never place a literal key in command arguments, shell history, checked-in MCP configuration, an agent prompt, or a log.

The examples pin the exact beta version so an agent cannot silently execute a newer release.

Cursor

Add this non-secret definition to .cursor/mcp.json:

{
  "mcpServers": {
    "proventools": {
      "command": "npx",
      "args": ["--yes", "@proventools/mcp@0.1.0-beta.3"]
    }
  }
}

Generic stdio client

{
  "command": "npx",
  "args": ["--yes", "@proventools/mcp@0.1.0-beta.3"]
}

The transport is JSON-RPC 2.0 over newline-delimited stdin/stdout. It implements initialize, tools/list, and tools/call.

Tools

• search_ideas({ query?, category?, difficulty?, page? })
• get_idea({ id })
• get_build_prompt({ id })
• whats_new()
• get_idea_evidence({ id, historyLimit? })
• get_validation_report({ id })
• get_credit_balance()
• recommend_ideas({ query, ...filters })
• shortlist_ideas({ query, ...filters })
• discover_ideas({ query, ...filters })
• compare_ideas({ ideaIds, query? })
• explain_idea_score({ id })

Evidence reads use stored PostgreSQL snapshots and cost zero credits. Intelligence tools may send natural-language input and selected stored idea fields to OpenAI for semantic retrieval and bounded synthesis when the server-side feature is enabled.

Every tool in this beta costs zero credits. It cannot request evidence refreshes, submit validations, spend credits, or start paid jobs. Existing validation reports and credit balances remain available as read-only data.

Network and process safety

The MCP process sends the ProvenTools API key only to approved production origins or HTTP loopback origins, rejects redirects, bounds request and output sizes, limits concurrent calls, and writes protocol messages only to stdout.
