MCP integrations

Small, typed tools that let coding agents work with external systems without turning every capability into another chatbot.

The design rule

A useful tool surface is narrow enough to understand, explicit about failure, and safe to call without hidden side effects. MCP is valuable here because it gives different agent clients a common contract.

Selected public work

browser and research tools
Structured access to public browser workflows, collection jobs, and reviewed results.
Claud-Ear
Local audio understanding exposed as agent-callable operations instead of a collection of manual commands.
apple-calendar-mcp
Scheduling and availability operations with explicit conflict checks and user-visible outcomes.
developer utilities
Small tools for repository, writing, and review workflows where structured inputs and outputs reduce ambiguity.

What I learned

The hard part is not wrapping a function. It is choosing the right capability boundary, describing it clearly enough for a model to use, and keeping consequential actions reviewable. Good tools reduce agent freedom at the exact place where a mistake would become expensive.

The public boundary

This page covers public and portfolio-safe integrations. Private business workflows, credentials, internal services, deployment details, personal data, and operational runbooks are intentionally excluded.

My rule for agent tools: read-only by default, explicit mutations, bounded outputs, and enough evidence for a person to verify what happened.
