概览

AI 生成的概览

Meld 是一个远程 MCP 服务器,用于创建短时有效的链接式桥接,让双方无需在聊天中粘贴即可交换工作上下文。

可以做什么
  • 创建桥接并附上一条说明,交代这次交换的用途与不适用之处,返回一个可私下发送的能力链接
  • 按代码向已有桥接追加回复,让对话始终留在同一条链接上
  • 按代码读取仍然有效的桥接,以明文返回说明和全部回复
  • 桥接在首次回复前开放 36 小时,之后每次回复重置 24 小时;读取不会改变计时
适用场景
适合两个人或两个代理需要通过私密链接交接工作上下文、而不是把内容粘贴到聊天里的场景,例如设计评审或一段应当自动过期的简短往来。
运行要求
远程端点 meld.mergeinc.workers.dev,使用 streamable HTTP;未声明需要账号、API 密钥、环境变量或请求头。README 另说明可用 Docker、带 Caddy 的 Compose 或 Python 自行部署。
安装前请注意
任何拿到链接的人都能读取和回复,托管方在桥接有效期内也能读取,因此明确不适合存放机密、密码或客户数据。桥接只保存在内存中:重启会丢失有效链接,已过期、已解散和不存在的代码都返回相同的 404。创建在试点期间据称免费。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Meld,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。

Web executable,通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.lemonaide152%2Fmeld/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。

README

meld — ephemeral context bridge

Don't meet. Meld.

Put working context on a capability URL. Neither side pastes the block. Party A creates the link. One note says what the exchange is for and what it is not for. A sends that URL to B privately. The conversation stays on that link.

The bridge stays open while the exchange is active. Until the first reply, the hop stays open 36 hours from creation. The first reply sets a 24 hour timer. Each later reply is kept. Each later reply resets that 24 hours. There is no maximum lifetime once replies have started. A read does not start the timer. A read does not reset the timer.

When the window ends, the host dissolves the meld. Dissolve deletes the bridge. The next request for that code is 404. A code that never existed is 404. An expired code is 404. The response is the same.

Host-readable while live. Anyone with the link can read it. Not for secrets. No accounts. No plaintext archive.

No AI in the loop. The host holds what you pour while the bridge is live. The host does not summarize the exchange. The host does not rewrite it. The host does not invent a reply. The host does not run a model on it.

Self-host is the path. This repository is the server, Caddy, and Docker setup.

Get started

bash
git clone https://github.com/lemonaide152/meld.git && cd meld && docker build -t meld . && docker run --rm -p 8080:8080 -e MELD_PUBLIC_URL=http://127.0.0.1:8080 meld

Then:

bash
curl -s -X POST http://127.0.0.1:8080/api/melds \  -H "Content-Type: application/json" \  -d '{"note":"For a design review. Not for passwords or customer data."}'

A sends the url to B privately. B replies with POST /api/melds/{code}/resolve. Keep talking on that same link.

Compose (local)

bash
cp .env.example .envdocker compose up -d --build

Same API on http://127.0.0.1:8080.

Compose + Caddy (public TLS)

Set MELD_SITE and MELD_PUBLIC_URL in .env, point DNS at the machine, open 80/443:

bash
docker compose --profile tls up -d --build

Python (no Docker)

bash
python3 -m venv .venv && . .venv/bin/activatepip install -r requirements.txtpython server.py

Publish an image

bash
docker build -t ghcr.io/lemonaide152/meld:latest .docker login ghcr.iodocker push ghcr.io/lemonaide152/meld:latest

API

EndpointMethodDescription
/api/meldsPOSTCreation. One note: what the exchange is for and what it is not for. Send note, or put that same text in context, for, and not_for. Open 36 hours from create until the first reply. A sends the URL to B privately.
/api/melds/{code}GETPlaintext while live: the note and every reply. Does not start or reset the timer. Unknown, dissolved, and expired are the same 404.
/m/{code}GETSame plaintext read. This is the capability URL. Link-preview crawlers get an expires-only card with no exchange. That card does not read the meld.
/api/melds/{code}/resolvePOSTAppend a reply on this same bridge. Keep talking on that link. The first reply sets a 24 hour timer. Each later reply is kept and resets that 24 hours. Unknown, dissolved, and expired are the same 404.

A client that still posts the older keys uses one note, the same text in each field:

json
{"context":"For a design review. Not for passwords or customer data.","for":"For a design review. Not for passwords or customer data.","not_for":"For a design review. Not for passwords or customer data."}

The read repeats that note in note, context_a, for, and not_for.

State is memory only. With no reply, 36 hours from creation deletes the meld. After a reply, 24 hours with no new reply deletes it. Dissolve removes the bridge. The server does not keep a record of that code. The next request is 404. A restart drops live links.

A background sweep runs every 5 minutes and deletes every expired bridge, even if nobody asks for that code again. Set MELD_SWEEP_SECONDS to change how often it runs. The default is 300. The server logs do not include bridge codes.

Spec

SPEC.md is the core spec for meld, currently version 2.0.0. It is the source of truth for behavior. GET /health reports the spec version this server targets, and python check_spec.py fails if SPEC.md and the server disagree on it. This server does not implement all of 2.0.0 yet (dissolve, the reply cap, MCP, and 128-bit codes are still missing), so /health reports "conformance": "partial".
