SQL

Read-only SQL querying + schema introspection over Postgres & SQLite, with a gated write mode.
Overview
A local MCP server that lets an assistant run read-only SQL queries and inspect schemas on Postgres and SQLite, with an opt-in write mode.
- What you can do
- Run read-only SQL queries against Postgres or SQLite connections and inspect database schemas, tables and columns to understand structure before querying. When write mode is explicitly enabled, run statements and multi-statement scripts that change data. Multiple named connections can be configured, each addressed separately.
- When to use it
- Useful when you want an assistant to explore or report on a Postgres or SQLite database, answer questions from its data, or make deliberate, gated changes to it without leaving the chat.
- Requirements
- Runs locally via npx (Node.js). Needs a connection URL in DB_CONN_default (postgres://… or sqlite:/abs/path); additional connections use DB_CONN_ . Write tools only work when DB_WRITABLE is set to 1 or true.
Installation
In SourceWeft
- Open SQL in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

Each server lives in its own folder under servers/ and publishes to npm as an independent package, while sharing tooling through an npm workspace. Connect them to any MCP client — Claude Desktop, Claude Code, Cursor, and more.

Servers
More on the way: a Spotify controller, and others.
Quickstart
Install
Every server ships through every common channel. For the Claude Code plugin, add the marketplace
once — /plugin marketplace add Abhishekkumar2021/mcp-suite — then install per the table. See each
server's README for full config.
notesdefaults to~/notes;filesrequiresFS_ROOTS(the directories it may touch). MCPB bundles install via Claude Desktop → Settings → Extensions.
Connecting to a client
Each server's README has full configuration instructions. As an example, to use the notes server with Claude Code:
Or with Claude Desktop (claude_desktop_config.json):
Architecture & conventions
A few principles hold across every server:
- Pure-JS/WASM by default; native only when genuinely required. Servers run via
npx/MCPB on any machine, so portable pure-JS/WebAssembly is strongly preferred and a native dependency is used only when genuinely required (gated + documented). In practice these servers are dependency-light:notesuses MiniSearch + WebAssembly embeddings,sqluses thesql.jsWASM SQLite engine, andfilesusesfast-globinstead of ripgrep.npm auditstays clean. - Sandbox-first, layered design. Each server keeps a thin
index.ts(tool registration only) over focused modules, with a single security boundary every path must pass through (realpath-containment, symlink-escape rejection, atomic writes). - Token-efficient by default. Pagination, head/tail/section reads, snippets, and compact graph refs keep tool output small.
- Automated, hands-off releases. A GitHub Release tagged
<server>-v<version>publishes to npm (with provenance), the official MCP registry, and attaches an MCPB bundle — all via OIDC, no secrets. - Tested in CI. Each server ships a committed
node:testsuite (unit + integration/security) run on every push.
Development
This is an npm workspaces monorepo.
Adding a new server
- Create
servers/<name>/with its ownpackage.json(unique npmname) and atsconfig.jsonthatextends: "../../tsconfig.base.json". - Put source in
servers/<name>/src/. - Run
npm installat the root so the workspace picks it up. - Add a row to the Servers table above.
All servers follow the naming standard (@abhishekmcp/<slug>). See CONTRIBUTING.md for detailed guidelines.
Publishing
Releases are automated. Cutting a GitHub Release tagged <server>-v<version> triggers
publish.yml, which — authenticated entirely via GitHub OIDC (no
NPM_TOKEN) — publishes the package to npm with provenance, registers it on the official MCP
registry, and builds + attaches the MCPB bundle to the release.

Contributions are welcome! Please read CONTRIBUTING.md and our Code of Conduct. Found a security issue? See SECURITY.md.

50% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
