Small tools for local systems, agents, and Go services.

This is a compact index for public projects I maintain. The pages are written for people trying to decide what a tool does, how to install it, and where its edges are.

Broker data and MCP

Canary

A local Interactive Brokers MCP server, CLI, and risk desk. It connects Claude Desktop, Claude Code, Cursor, Zed, and shell workflows to account and market context from IB Gateway or TWS.

Claude Desktop MCP Bundle is the fastest install path.
Standard builds and MCP are read/preview-only; gated broker writes require a separate opt-in trading build.
Useful for portfolio review, options diagnostics, scanners, breadth, gamma, and regime context.

Go HTTP library

hyperserve

A small net/http-shaped server for Go services. It keeps the dependency tree flat, adds method-aware routes, typed binding and validation, and can expose an MCP control plane from the same binary when that is useful.

Built on the standard library, with one runtime dependency.
Includes middleware, graceful shutdown, static-file sandboxing, WebSocket, SSE, and JSON-RPC pieces.
MCP support is opt-in, with HTTP, SSE, and stdio transports sharing one protocol surface.
