​
Overview

Pond3r provides a Model Context Protocol (MCP) server that lets AI agents query curated crypto datasets directly. The server uses Streamable HTTP transport, so it works with Claude Desktop, Claude Code, Cursor, and any MCP-compatible client.

​
Getting Your API Key

1

Create an account

Sign up at makeit.pond3r.xyz if you haven’t already.
2

Generate an API key

Go to makeit.pond3r.xyz/api-keys and generate a new key.
Keep your API key secure. Never expose it in client-side code or public repositories.

​
Setup with Claude Code

Run this command in your terminal to add the Pond3r MCP server: 
claude mcp add pond3r-data \
  --transport http \
  https://mcp.pond3r.xyz/mcp \
  --header "Authorization: Bearer your_api_key_here"
The tools will be available immediately in your Claude Code session.

​
Setup with Claude Desktop

Add the following to your Claude Desktop MCP configuration file (claude_desktop_config.json): 
{
  "mcpServers": {
    "pond3r": {
      "type": "http",
      "url": "https://mcp.pond3r.xyz/mcp",
      "headers": {
        "Authorization": "Bearer your_api_key_here"
      }
    }
  }
}
Restart Claude Desktop and the Pond3r tools will be available in your conversations.

​
Setup with Cursor

In Cursor, go to Settings > MCP Servers and add a new server:
  • URL: https://mcp.pond3r.xyz/mcp
  • Headers: Authorization: Bearer your_api_key_here

​
Setup with Other Clients

For any MCP-compatible client that supports Streamable HTTP transport, send POST requests to: 
https://mcp.pond3r.xyz/mcp
Pass your API key as a Bearer token in the Authorization header: 
Authorization: Bearer your_api_key_here

​
Available Tools

Once connected, your AI agent has access to three tools:
ToolDescription
list_datasetsList all available datasets and their tables
get_schemaGet column names, types, and descriptions for a dataset
queryExecute a read-only SQL query against a dataset
The agent will automatically discover schemas and available data — you just need to ask your question in natural language.

​
Query Tool

The query tool executes read-only SQL against Pond3r datasets. A few things to note:
  • SELECT only — write operations are not allowed.
  • Use bare table names — e.g. SELECT * FROM stablecoin_yields, not fully qualified paths.
  • Results are capped at 10,000 rows — use LIMIT or WHERE filters for large datasets.
  • Cost is estimated before execution — queries that exceed your tier limits are rejected before running.

​
Available Datasets

The MCP server provides access to the following curated datasets:

​
Prediction Markets

Periodic snapshots of Polymarket prediction markets with prices, volume, liquidity, and resolution status. Includes a pre-computed view linking markets to CLOB token IDs for crypto up/down markets.Tables: polymarket_trades, polymarket_resolutions, polymarket_markets, polymarket_market_tokensBest for: Market analysis, resolution tracking, crypto derivatives research
Enriched Polymarket crypto 5m/15m market trades with pre-computed price, size, side, and market timing. Filtered to BTC, ETH, SOL, XRP up/down markets only.Tables: crypto_tradesBest for: Trade flow analysis, price discovery, market microstructure
One row per resolved crypto 5m/15m market with outcome and metadata. Includes volume, liquidity, and resolution timestamps.Tables: crypto_market_resolutionsBest for: Backtesting strategies, outcome prediction, market efficiency analysis
One row per crypto 5m/15m market with aggregated trade stats, price stats, resolution outcome, and orderbook stats. Primary view for strategy backtests.Tables: market_summaryBest for: Strategy development, market behavior analysis, performance research
Enriched orderbook snapshots with time-series features (changes between consecutive snapshots). Built with LAG window functions for detecting liquidity changes.Tables: orderbook_featuresBest for: Liquidity analysis, market making research, microstructure studies
For each resolved 15-minute market, counts how many overlapping 5-minute markets resolved up vs down, and whether this predicted the 15-minute outcome.Tables: cross_timeframe_signalsBest for: Multi-timeframe analysis, signal generation, predictive modeling
Sequential market patterns tracking consecutive same-outcome streaks and whether they break. Useful for mean-reversion studies.Tables: streak_featuresBest for: Pattern recognition, momentum/reversion analysis, sequence modeling

​
DeFi Yields & Lending

Hourly snapshots of stablecoin DeFi yields across lending protocols. TIME-SERIES TABLE with multiple snapshot rows per pool — always use deduplication.Tables: stablecoin_yieldsBest for: Yield farming, protocol comparison, APY optimization
This is a time-series table. Always use QUALIFY ROW_NUMBER() OVER (PARTITION BY blockchain, protocol_name, token_symbol ORDER BY data_collection_timestamp DESC) = 1 to get the latest snapshot per pool.
Daily aggregated pool yields enriched with 7d/30d rolling stats, momentum indicators, spike detection, and rankings. Built from yield_pool_daily.Tables: yield_pool_featuresBest for: Trend analysis, risk-adjusted returns, yield stability assessment
Daily Morpho individual market data enriched with rolling stats, utilization trends, and rankings. Includes supply APY, utilization, and flow metrics.Tables: morpho_market_featuresBest for: Morpho-specific strategies, capital efficiency research, utilization analysis
Daily Morpho vault data enriched with APY features, actual share price returns, and rankings. Tracks net APY after fees and cumulative returns.Tables: morpho_vault_featuresBest for: Vault comparison, return tracking, fee impact analysis
Daily Aave rates enriched with rolling stats and cross-chain ranking. Identifies best chains per token and arbitrage opportunities.Tables: aave_rate_featuresBest for: Cross-chain optimization, rate comparison, chain selection

​
Example Conversations

Once the MCP server is connected, you can ask your AI agent questions like:

​
Prediction Markets

What's the win rate for BTC 5-minute up markets in the last week?

Show me the top 10 most active Polymarket traders by volume.

Find 15-minute markets where all three 5-minute sub-markets agreed on direction.

​
DeFi Yields

What are the top 5 stablecoin yields on Ethereum right now?

Compare USDC yields across Aave, Morpho, and other protocols on Arbitrum.

Show me pools with APY > 10% and low volatility (cv_30d < 0.3).
The agent will use the list_datasets and get_schema tools to understand what’s available, then write and execute SQL via the query tool.

​
Troubleshooting

Make sure your API key is valid and correctly set. Check that your client is sending the Authorization header with every request.
The server requires bare table names (e.g. stablecoin_yields). Do not include project or dataset prefixes in your SQL.
You’ve hit your daily or monthly spend cap. Wait for the limit to reset or upgrade your plan for higher limits.
