How do I install the fish mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `FISH_BRIDGE_BACKEND`, `GEMINI_API_KEY`, `ANTHROPIC_API_KEY`, `OPENAI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Fish MCP Server?

Compresses AI chat sessions into a typed knowledge graph. Local/offline via Ollama.

What the server does

Converts raw AI chat (40k+ tokens) into a compact typed knowledge graph (~300–800 tokens) and writes it to .github/copilot-instructions.md or CLAUDE.md — automatically included in every AI turn across all modes (ask, edit, agent). No MCP server required for the core workflow.
