Neon 官方 MCP server（MIT）：agent 管 Neon 项目、建分支、跑 SQL。特色是分支模型——agent 可以在库副本上试改动；但默认连接面照旧，按「它能执行 SQL、管理 key 能删项目」设防。诚实标注：旧 docs 路径 404，现役以仓为准。

Neon's official MCP server (MIT): agents manage Neon projects, create branches, run SQL. The signature is the branch model — agents can try changes on a copy; but the default connection surface is unchanged, so defend as if it can execute SQL and the management key can delete projects.

适合与不适合When to use it, when not to

适合：Neon/serverless Postgres 栈的 agent 开发流、分支隔离试验。不适合：非 Neon 的 Postgres；要硬只读边界。

Fits: agent dev flows on Neon/serverless Postgres, branch-isolated experiments. Not a fit: non-Neon Postgres (it manages its own platform); hard read-only boundaries.

出品属地Origin: 国外出品foreign-made　Neon, Inc.（美国，现归 Databricks——vendor 口径按官方现行主体写 Neon）。Neon, Inc. (US; now under Databricks — the vendor line follows Neon as the current official product owner).
国内使用Direct access: 直连不可达direct blocked　github.com 直连实测 000（波动，同日代理可达 200）；neon.com 直连未单独测。github.com measured 000 direct (fluctuating; 200 via proxy the same day); neon.com not individually measured.
备案状态CAC filing: 未见于备案名单not in filing list：未见于网信办公示名单（2026-10-21 检索）；该产品未面向大陆公众提供服务，备案不适用。not in the CAC public registry (searched 2026-10-21); the product does not serve the mainland public, so filing does not apply.

备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

模型与开放条件Model & openness: 它自己不调模型——被 MCP 客户端调用的接口实现。它把 Neon（serverless Postgres）的管理 API 与数据库操作包装成工具给 agent 用。
It calls no model itself — an interface implementation called by MCP clients. It wraps Neon's (serverless Postgres) management API and database operations as tools for agents.
运行位置Where it runs: 本地进程（npx stdio）+ 官方托管远程线；GitHub 659★，最近推送 2026-10-29（API 核验）。旧 docs 路径（neon.com/docs/ai-and-mcp/mcp-server）直抓 404——现役以仓为准。
A local process (npx stdio) + an official hosted remote line; GitHub 659★, last push 2026-10-29 (API verified). The old docs path (neon.com/docs/ai-and-mcp/mcp-server) direct-fetched 404 — the current line is the repo itself.
本地文件Local files: 不读写本机项目文件——作用域是 Neon 云端项目/分支与数据库。
Reads and writes no local project files — the scope is Neon cloud projects/branches and databases.
关机后的任务Tasks after shutdown: stdio 随客户端生死；Neon 的分支（branch）能力是它特色——agent 可建库分支做隔离试验。
stdio lives and dies with the client; Neon's branch capability is its signature — an agent can create database branches for isolated experiments.
工具与扩展Tools & extensions: 项目管理、分支创建/删除、数据库查询执行、schema 查看等；写能力齐全（建分支、执行 SQL）。完整清单以仓 README 为准。
Project management, branch create/delete, database query execution, schema inspection, etc.; write capabilities are complete (create branches, execute SQL). The complete inventory follows the repo README.
上下文与记忆Context & memory: 无跨会话记忆——状态在 Neon 项目本身。
No cross-session memory — state lives in the Neon project itself.
权限与限制Permissions & limits: 两条凭据：Neon API key（管理面：项目/分支）+ Postgres 连接串（数据面：SQL）。 Neon 的分支模型给了「agent 在副本上试」的隔离玩法——但默认连主分支时写面照旧，按「它能执行 SQL」设防。
Two credentials: a Neon API key (management surface: projects/branches) + a Postgres connection string (data surface: SQL). Neon's branch model enables the "agent tries things on a copy" isolation play — but when connected to the main branch by default the write surface is unchanged; defend on the assumption "it can execute SQL".
适合什么任务Best for: 适合：Neon 栈的 agent 开发流（建分支→试改→合并）、serverless Postgres 管理接 agent。不适合：非 Neon 的 Postgres（它管自家平台）；要硬只读边界。
Fits: agent dev flows for the Neon stack (create branch→try changes→merge), hooking serverless Postgres management into an agent. Not a fit: non-Neon Postgres (it manages its own platform); hard read-only boundaries.
传输方式Transport: stdio（npx）为主 + 官方托管远程线（细节以仓 README 为准，未逐条核验）。核验：仓与 GitHub API（2026-10-21）。
stdio (npx) is primary + an official hosted remote line (details follow the repo README, not verified item by item). Verified: the repo and GitHub API (2026-10-21).
认证机制Authentication: Neon API key（管理面）+ Postgres 连接串（数据面）两路线。
Two routes: Neon API key (management surface) + Postgres connection string (data surface).
权限范围Permission scope: 管理面：项目/分支增删查；数据面：SQL 执行（含写/DDL）。无工具级审批机制的官方说明；分支模型是结构性隔离手段而非审批层。
Management surface: project/branch add/delete/query; data surface: SQL execution (including writes/DDL). No official docs for a tool-level approval mechanism; the branch model is a structural isolation means, not an approval layer.

头号误解Top misconception

找 neon.com/docs/ai-and-mcp/mcp-server——该路径 404（2026-10-21 直抓），现役以 neondatabase 仓为准Looking for neon.com/docs/ai-and-mcp/mcp-server — that path 404s (direct-fetched 2026-10-21); the live line is the neondatabase repo
把「分支隔离」当默认安全——默认操作面跟着连接配置走，主分支照写不误Treating 'branch isolation' as safe by default — the operating surface follows connection config; the main branch still gets writes
管理 key 与数据连接串两权限面混配——管理面能删项目，数据面能改数据Mixing the management key with the data connection string — the management surface can delete projects; the data surface changes data
