概览

AI 生成的概览

本地 MCP 服务器，将 AI 对话会话压缩为带类型的知识图谱，并把精简的上下文块写入项目指令文件。

可以做什么
在 agent 模式下实时把对话轮次记录进会话知识图谱，可选由 LLM 抽取后端完成类型标注与去重。读取当前上下文、聚焦子集以及活跃或延后节点列表。添加节点、标记条目已解决，并导出或导入会话图谱文件。配套 CLI 可摄取 Copilot 记录、粘贴文本、文档、代码库、依赖文件、测试输出、IaC 与 OpenAPI 规范，再把图谱编译进 copilot-instructions.md 或 CLAUDE.md。
适用场景
适合需要跨轮次或跨工具延续长对话、又不想重复发送数万 token 的场景，也适合把决策、任务和错误以结构化、可编辑的图谱保存在项目指令文件中。基于文件的工作流并不需要这个 MCP 服务器。
运行要求
以 Python 包 fish-bridge-mcp 形式本地运行，可通过 uv、uvx 或 pip 安装；仅限桌面环境。需要抽取后端：本地 Ollama，或使用 ANTHROPIC_API_KEY、GEMINI_API_KEY、OPENAI_API_KEY 配置的云端后端。云端后端按轮次计费。
安装前请注意
云端后端会把对话内容发送给 Anthropic、Google 或 OpenAI，并按轮次收费；本地 Ollama 后端可同时避免这两点。服务器会写入 .github/copilot-instructions.md 或 CLAUDE.md 等项目文件，这些内容会进入之后的每一轮 AI 对话，请检查写入内容。API 密钥从环境变量读取。

安装

在 SourceWeft 中

  1. 打开 控制台中的 fish-bridge — Session Knowledge Graph，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

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):

bash
# 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-...
# Everythinguv 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:

json
{ "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)
bash
pip install fish-bridge-mcppip install "fish-bridge-mcp[gemini]"   # with Gemini backendpip install "fish-bridge-mcp[claude]"   # with Claude backendpip install "fish-bridge-mcp[all]"      # everything

2-minute quickstart

bash
# 1. Initialize for your projectfish-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 graphfish-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):

json
{  "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:

json
{ "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
