Overview

Description from the maker (original English)

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

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory
  • You need to fill in: ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "fish-bridge": {
      "command": "uvx",
      "args": [
        "fish-bridge-mcp"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "OPENAI_API_KEY": "your-value",
        "GEMINI_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add fish-bridge --env ANTHROPIC_API_KEY=your-value --env OPENAI_API_KEY=your-value --env GEMINI_API_KEY=your-value -- uvx fish-bridge-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "fish-bridge": {
      "command": "uvx",
      "args": [
        "fish-bridge-mcp"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "OPENAI_API_KEY": "your-value",
        "GEMINI_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "fish-bridge": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "fish-bridge-mcp"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "OPENAI_API_KEY": "your-value",
        "GEMINI_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • ANTHROPIC_API_KEY secret env
    API key for Claude extraction backend (omit when using local/Ollama)
  • OPENAI_API_KEY secret env
    API key for OpenAI extraction backend (omit when using local/Ollama)
  • GEMINI_API_KEY secret env
    API key for Gemini extraction backend (omit when using local/Ollama)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is fish-bridge — Session Knowledge Graph safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

fish_bridge

Session-scoped knowledge graph engine for AI chat context compression.

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.

Raw session (40k tokens) → [fish_bridge] → Compressed graph (350 tokens)

written to copilot-instructions.md picked up by every AI turn automatically

Install

Don't have uv? Get it first: curl -LsSf https://astral.sh/uv/install.sh | sh (macOS/Linux) or see uv docs. It replaces pip + pipx + pyenv in one tool — no virtualenv management needed.

Recommended — `uv tool install` (installs both the fish-bridge CLI and fish-bridge-mcp MCP server on your PATH):

# Local Ollama backend — free, offline (requires Ollama running)

uv tool install fish-bridge-mcp

Gemini backend (~$0.0002/turn, ~95% quality — recommended cloud option)

uv tool install "fish-bridge-mcp[gemini]" export GEMINI_API_KEY=...

Claude backend (~$0.002/turn, ~97% quality)

uv tool install "fish-bridge-mcp[claude]" export ANTHROPIC_API_KEY=sk-ant-...

OpenAI backend (~$0.0003/turn, ~93% quality)

uv tool install "fish-bridge-mcp[openai]" export OPENAI_API_KEY=sk-...

Everything

uv tool install "fish-bridge-mcp[all]"

After install, two commands are available on your PATH:

  • `fish-bridge` — the main CLI (ingest, compile, show, serve, ...)
  • `fish-bridge-mcp` — the MCP server for VS Code agent mode

MCP config only (no permanent install needed): use uvx directly in your .vscode/mcp.json — it downloads and runs the MCP server on demand:

{ "command": "uvx", "args": ["fish-bridge-mcp"] }

See the MCP server section below for the full config.

Traditional pip install (for embedding fish-bridge as a library in your own Python project)

pip install fish-bridge-mcp

pip install "fish-bridge-mcp[gemini]" # with Gemini backend pip install "fish-bridge-mcp[claude]" # with Claude backend pip install "fish-bridge-mcp[all]" # everything

</details>

2-minute quickstart

# 1. Initialize for your project

fish-bridge init --tool copilot --project ./

2. Ingest the latest Copilot session (auto-discovers JSONL on macOS/Linux/Windows)

fish-bridge ingest --source copilot

3. View the graph

fish-bridge show

4. Compile to your instructions file (done automatically after ingest)

fish-bridge compile

That's it. .github/copilot-instructions.md now contains a ~350-token compressed summary of your session, replacing raw history in every future turn.

MCP server (optional — agent mode only)

The MCP server adds real-time record_turn capture when using VS Code agent mode. It is not required — the file-based workflow above works in all modes without it.

Add to .vscode/mcp.json (uses uvx — no prior install needed):

{

"servers": { "fish-bridge": { "command": "uvx", "args": ["fish-bridge-mcp"], "env": { "FISH_BRIDGE_BACKEND": "gemini", "GEMINI_API_KEY": "${env:GEMINI_API_KEY}" } } } }

If you used uv tool install fish-bridge-mcp, you can also reference the installed binary directly:

{ "command": "fish-bridge-mcp" }

See examples/ for Claude Desktop, Cursor, and Windsurf configs.

MCP tools: record_turn, get_context, get_focus, mark_resolved, add_node, export_session, import_session, show_active, list_deferred

Ingest sources

SourceCommandWhat it ingests
Copilotingest --source copilotVS Code Copilot JSONL transcript (auto-discovered)
Pasteingest --source pasteAny chat text — universal fallback
Documentmerge --source documentMarkdown, JSON, YAML specs and ADRs
Codebasemerge --source codebaseGit commits + README + HANDOVER
Obsidianmerge --source obsidianVault notes with wikilinks and frontmatter
Sessionmerge --source sessionPrior .chatgraph.json export
Depsmerge --source depspackage.json, pyproject.toml, Cargo.toml, go.mod, Gemfile, pom.xml
Test outputmerge --source testoutJest JSON, pytest JSON, JUnit XML — error nodes per failing test
IaCmerge --source iacTerraform, CDK (synth output), CloudFormation, docker-compose
OpenAPImerge --source openapiOpenAPI 3.x / Swagger 2.0 / AsyncAPI specs

How it works

  1. Ingest — reads raw chat turns from JSONL (Copilot), paste, or any file format
  2. Extract — LLM extracts typed nodes (questions, decisions, errors, tasks, skills, files) and edges
  3. Dedup — semantic similarity merges near-duplicates; conflict detection flags status reversals
  4. Compile — graph is compressed to ~300–800 token XML/markdown block
  5. Write — block is written to .github/copilot-instructions.md (or CLAUDE.md)
  6. Deliver — AI tool reads the file automatically on the next turn — no injection, no agent required
