build and configure GenAI MCP servers

Covers LLM MCP API Development Google Cloud

Description

Builds the mcp-genmedia Go MCP servers (nanobanana, veo, lyria, gemini-multimodal, chirp3-hd, avtool) from source and wires them into settings.json. Use this skill whenever the MCP tools are missing or broken — typically at the start of a new session, after a container restart, or when /tmp has been wiped. The prebuilt binaries in /workspace/.local/bin/ have no exec bit and live on a noexec mount; this skill compiles fresh executables into /tmp/bin/ where execution is allowed.

Build mcp-genmedia from Source

When to invoke this skill

  • MCP tools (nanobanana, veo, lyria, etc.) are not responding or missing from tool list
  • /tmp has been wiped (container restart, new session)
  • settings.json still points to /workspace/.local/bin/ binaries (which are not executable)
  • Any exec format error or permission denied when Claude Code tries to start an MCP server

How it works

The prebuilt binaries shipped in /workspace/.local/bin/ lack the executable bit and live on a noexec filesystem mount — they can never be run directly. The source code for all six servers lives in the upstream repo. This skill clones that repo, downloads Go if needed, compiles the servers into /tmp/bin/ (which is exec-allowed), and updates settings.json to point there.

Step-by-step procedure

1. Run the build script

bash /workspace/.claude/skills/build-mcp-genmedia/scripts/build.sh
