consolelog-mcp

Deterministic developer tools for AI agents, over the Model Context Protocol. The same engine that powers consolelog.tools and its CLI — exposed so your coding agent stops guessing and starts calling.

It's a local stdio server, no account or key, and it runs via npx:

npx -y consolelog-mcp

Add it to your client

Claude Code

claude mcp add consolelog -- npx -y consolelog-mcp

Cursor / Claude Desktop / Windsurf — add to the client's MCP config:

{
  "mcpServers": {
    "consolelog": {
      "command": "npx",
      "args": ["-y", "consolelog-mcp"]
    }
  }
}

On native Windows (not WSL), wrap the launcher in cmd /c:

{ "mcpServers": { "consolelog": { "command": "cmd", "args": ["/c", "npx", "-y", "consolelog-mcp"] } } }

See consolelog.tools/mcp for every client (VS Code, Codex, Antigravity, opencode) and a copy-paste config for each.

Why curated (~25 tools, not 200+)

Every tool an MCP server exposes costs the calling agent context on each request, so a bloated server makes agents slower and less accurate. This server includes only what a language model is unreliable at — hashing, HMAC, password hashing, random IDs, regex execution, color math — or what's cheaper to offload than to regenerate: JSON/YAML/SQL/XML/CSV formatting and conversion, and codegen (TypeScript / Zod) from sample data.
