# langbot-mcp <!-- mcp-name: ai.langbot/langbot --> MCP server for [Langbot](https://langbot.ai), the data and simulation layer for every market on Kalshi and Polymarket: search any market and read its price history, compare the same question across both venues, replay past events against the order books Langbot recorded, and, for markets that settle on what is said (mention markets are one example), the live record of the event with verifiable receipts.

Over local stdio, `search_markets` and `get_market_history` work without a token. ```bash uvx langbot-mcp # stdio — what Claude Code / Cursor / Claude Desktop / Codex run langbot-mcp --http # streamable HTTP on 0.0.0.0:8001 at /mcp (hosted: https://mcp.langbot.ai/mcp); multi-tenant, token per request langbot mcp install claude-code # one-command install (also: cursor, claude-desktop, codex, all) ``` Manual client entry: ```json { "mcpServers": { "langbot": { "command": "uvx", "args": ["langbot-mcp"], "env": { "LANGBOT_API_TOKEN": "lb_…" } } } } ``` Hosted, for clients that send headers (Cursor, Claude Code `--transport http`): ```json { "mcpServers": { "langbot": { "url": "https://mcp.langbot.ai/mcp", "headers": { "Authorization": "Bearer lb_…" } } } } ``` **Auth.** Each tool's `_meta` has `langbot/auth` (`none` | `token`: what the feed needs, which is what applies over local stdio) and `langbot/auth_hosted` (always `bearer`).
