PolyBridge MCP v0.2.7

Download

Download polybridge-mcp-v0.2.7.mcpb from Assets below and open it with Claude Desktop to install.

Do not download “Source code” unless you are a developer.

What it does

PolyBridge MCP gives Claude Desktop probabilistic foresight from live prediction markets.

Ask a question about the future, even when no exact market exists. PolyBridge finds relevant markets, synthesizes the evidence, and returns a read-only forecast with probabilities and source-market metadata.

No API key is required at anonymous limits. Add POLYBRIDGE_API_KEY only for higher usage.

PolyBridge MCP is read-only. It does not trade or move funds.

polybridge-mcp-v0.2.4

PolyBridge MCP v0.2.4

This release updates the local Claude Desktop MCPB package so omitted Search dimensions now default to all supported dimensions:

• direct
• upstream
• downstream
• correlated

This matches the backend Search default behavior introduced in the platform repo.

Notes

• Search scores remain relevance/ranking scores, not probabilities.
• Local MCPB Forecast still uses POLYBRIDGE_API_KEY. Hosted MCP is separate and now works without a key for Search and Forecast at anonymous limits.
• This release does not add sports-aware routing or weak-match warnings.

PolyBridge MCP v0.2.3

PolyBridge MCP v0.2.3

This patch release adds local MCPB attribution for Search and Forecast calls.

What changed

• Local MCPB requests now identify themselves with:
  • X-Polybridge-Channel: local_mcpb
  • X-Polybridge-Tool: polybridge_search | polybridge_forecast
  • X-Polybridge-Client: polybridge-mcp
  • X-Polybridge-Client-Version: 0.2.3
• Existing POLYBRIDGE_ATTRIBUTION_CODE behavior is preserved.
• No trusted OAuth client ID is sent in local mode.
• No local machine/user metadata is collected or sent.
• Hosted MCP behavior is unchanged.
