Need help deploying mcp-engineering?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/chnetajibc-mcp-engineering
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# mcp-engineering Build the tool the agent wishes existed: workflow-shaped, narrowly permissioned, loudly correct on misuse. ## Activate when - Creating or extending an MCP server (Python FastMCP or TypeScript). - Deciding tool boundaries, naming, or error formats. ## Do NOT activate for - Auditing an existing MCP server for security (see security/agent-security). ## Procedure 1. Scope: one tool per user-meaningful workflow step, not per internal function; prefer fewer, composable tools over exhaustive coverage. 2. Naming: `verb-object` names, typed inputs, documented preconditions; errors state what was wrong, what was expected, and the safe retry. 3. Permissions: least privilege per tool; destructive tools require confirmation params and log intent. 4. Versioning: additive changes first; breaking tool-shape changes get a version bump + migration note. 5. Evaluate: scripted happy-path + misuse + adversarial-input runs before shipping. 6. Verify: run the eval script, exercise tools from a real client, and confirm logs show who called what. ## References - Related: `../agent-architecture/`, `../../security/agent-security/`.
