MCP tools for Claude

dataset-mcp: five tools over the dataset catalog

The server behind this catalog. Five tools: list_datasets, get_dataset_info, get_sample, query_dataset, and get_stats. query_dataset filters and paginates the full released files (149,673 rows across five datasets), 100 rows per call, with =, contains, gt, and lt operators. get_stats returns row counts, numeric min/max/mean, and top-N frequencies. Files download once from a public GitHub release into ~/.cache/dataset-mcp/ and are re-verified against SHA-256 on every load.

The README's config for claude_desktop_config.json, plain form (npm 10 and 11):

{
  "mcpServers": {
    "dataset-mcp": {
      "command": "npx",
      "args": ["-y", "github:jayjex/dataset-mcp"]
    }
  }
}

npm 12 refuses git-based installs (EALLOWGIT), so the README also ships the flag-carrying form:

{
  "mcpServers": {
    "dataset-mcp": {
      "command": "npx",
      "args": ["--allow-git=all", "-y", "github:jayjex/dataset-mcp"]
    }
  }
}

Registry: io.github.jayjex/dataset-mcp, version 1.1.0, active. Repo: github.com/jayjex/dataset-mcp. Full tool docs with a captured session: MCP server for datasets.

earn-bounty-scanner: three tools over the live Earn feed

Reads superteam.fun at call time, so rewards and deadlines are current. search_bounties(query) matches keywords and returns the full bounty description text, not a teaser. get_bounty(id) pulls one listing's complete details. recent_bounties() lists currently OPEN bounties, newest first. Every response carries agentAccess: AGENT_ALLOWED means an agent may submit, HUMAN_ONLY means bot submitters are barred.

The README's config for claude_desktop_config.json:

{
  "mcpServers": {
    "earn-bounty-scanner": {
      "command": "npx",
      "args": ["-y", "earn-bounty-scanner"]
    }
  }
}

That entry expects the npm package, which is not on the registry yet. Until it ships, build from the repo (git clone, npm install, npm run build) and point the config at the local build, the same shape our other READMEs use:

{
  "mcpServers": {
    "earn-bounty-scanner": {
      "command": "node",
      "args": ["/absolute/path/to/earn-bounty-scanner/dist/index.js"]
    }
  }
}

Registry: io.github.jayjex/earn-bounty-scanner, version 1.0.0, active. Repo: github.com/jayjex/earn-bounty-scanner.

solana-research-library: four tools over a Solana research database

25 Solana and web3 earning platforms, each field-probed with a verdict (LIVE-RAIL, USER-GATED, CONDITIONAL-PASS, WATCHLIST, DEAD), the exact payout rail, and the KYC gate. Four tools: list_topics, get_topic, search_topics, and stats. The database ships inside the package, so tools answer instantly and an upstream outage cannot fail a call.

The README's config for claude_desktop_config.json:

{
  "mcpServers": {
    "solana-research-library": {
      "command": "node",
      "args": ["/absolute/path/to/solana-research-library/dist/index.js"]
    }
  }
}

dist/ is committed to the repo, so after git clone and npm install the path above exists even before a build.

Registry: io.github.jayjex/solana-research-library, version 1.0.0, active. Repo: github.com/jayjex/solana-research-library.
