Slack MCP Server vs SQLite MCP Server

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Slack MCP Server MCP Servers	SQLite MCP Server MCP Servers
Tagline	Archived reference MCP server that lets Claude and other MCP clients read and post in a Slack workspace via a bot token.	Reference MCP server for querying and analyzing SQLite databases through Claude and other MCP clients.
Category	MCP Servers	MCP Servers
Pricing	Free· Free / open-source (MIT). Requires a Slack workspace and a Slack bot token; Slack itself is free/paid.	Free· Free / open source (MIT). No usage fees; runs locally against a SQLite file you control.

Pros	Official reference implementation from the modelcontextprotocol project — small, readable TypeScript that documents the MCP tool pattern well Covers the eight highest-value Slack primitives (list, post, reply, react, history, thread, users, profile) with minimal ceremony Ships as both an npx package and a Docker image, so it drops straight into Claude Desktop, Cursor, or any MCP client with a JSON config snippet Standard Slack bot-token auth (xoxb-) with clearly scoped OAuth permissions — easy to reason about and to revoke Open-source under MIT, so forking or vendoring for internal hardening is straightforward Good starting point for learning how to write your own MCP server against a REST API	Zero-config local database access for any MCP client — point it at a .db file and Claude can query, schema-introspect and write immediately. Clean, minimal tool surface (six tools) that maps cleanly to how an LLM actually reasons about a database. Novel `append_insight` + `memo://insights` pattern gives the model a persistent scratchpad for multi-turn analysis. MIT-licensed and open source, so it doubles as a canonical example for building your own MCP server. Multiple install paths — uv, Docker, VS Code one-click — cover most developer setups. No API keys, no cloud, no per-query cost; everything runs on your machine against a file you own.
Cons	Archived by the maintainer on 29 May 2025 — no upstream bug fixes, security patches, or Slack API compatibility updates Read-only surface for channels (public channels only by default) and no DM, private-channel, search, files, or canvas support out of the box No pagination helpers or rate-limit backoff beyond what the Slack SDK provides, so bulk history pulls in large workspaces can be fragile Requires a workspace admin to install a bot app and mint a token, which is a real blocker in locked-down enterprise Slack tenants Bot-token model means every action is attributed to the bot user, not the human operating the assistant, which complicates audit trails	Repository was archived on 29 May 2025 — no more upstream fixes, security patches or new features. Exposes `write_query` and `create_table` to the model, so a careless prompt can mutate or drop data; there is no built-in read-only mode or row-level safety. SQLite-only — no Postgres, MySQL, DuckDB or cloud-warehouse support; you need a different MCP server for those. No authentication, quota or audit layer; intended for local single-user use, not shared/multi-tenant deployments. Insight-memo state lives in the running server process, so it does not survive restarts or multiple concurrent clients cleanly.
