The Notion MCP Server is the official integration from Notion that connects AI assistants directly to your Notion workspace via the Notion REST API. With 4,580+ GitHub stars, it is the canonical MCP tool for bringing Notion's knowledge management capabilities into Claude Desktop, Cursor, Windsurf, and any MCP-compatible client. The server exposes a rich set of tools: search your entire workspace by keyword and return matching pages and databases; retrieve full page content and block trees; create new pages inside any parent page or workspace section; update, append, or delete block content on existing pages; list all databases your integration has access to; query database entries with filter and sort parameters; retrieve individual blocks or nested children by block ID; and add comments to pages. Authentication uses a Notion integration token — create an internal integration at notion.so/my-integrations, share specific pages or databases with it, and set NOTION_TOKEN in your environment (the older OPENAPI_MCP_HEADERS form still works). Install with a single npx command. The Notion MCP Server is especially powerful for AI workflows that span documentation retrieval, project planning, and knowledge capture — Claude can read product specs from Notion, draft new pages from conversation output, log structured data into databases, and search across thousands of notes without any manual copy-paste.

The Linear MCP server connects your AI assistant directly to Linear's project management platform via an officially hosted remote endpoint at mcp.linear.app — no local installation required. This is Linear's own first-party server, authenticated with OAuth 2.1 and centrally managed so you always run the latest version without updates. Available tools let you search issues by keyword, team, cycle, or filter; create new issues with title, description, and assignee; update status, priority, labels, and comments; and navigate Linear's project and cycle structure. In Claude Code, add it with: `claude mcp add --transport http linear-server https://mcp.linear.app/mcp`, then run /mcp to complete the OAuth flow. For older clients, use the mcp-remote bridge for backwards compatibility. Claude Desktop and Claude.ai users can connect via Settings > Connectors. Cursor and Codex have native support via their MCP config. Linear is used by thousands of engineering and product teams to plan, track, and ship software — the Linear MCP server brings that data into every AI-powered workflow without copy-paste or context-switching.

The HubSpot MCP Server is HubSpot's hosted, official Model Context Protocol endpoint for Smart CRM data, reachable at https://mcp.hubspot.com and authorised with OAuth 2.0 — there is no package to install and no token to paste into a config file. Access is scoped by a HubSpot user-level app: you create one with read (and optionally write) scopes for the CRM objects you want an assistant to reach, then complete the OAuth flow from inside your client. Read and write coverage spans contacts, companies, deals, tickets, carts, products, orders, line items, invoices, quotes, subscriptions and lists, plus engagements — calls, emails, meetings, notes and tasks — and the associations between them. Organisational context (users, teams, reporting structures, owners, roles, seats) and marketing content (campaigns and their metrics, landing pages, website pages, blog posts) are read-only. Custom Sensitive Data Properties and Personal Health Information are excluded regardless of scopes. Two other things share the name and are commonly confused with this one: the Developer MCP server, installed locally with `hs mcp setup` from the HubSpot CLI and aimed at building HubSpot apps rather than querying CRM records, which requires Developer Platform v2025.2; and the original May 2025 public beta, an npm package configured with a private-app access token, which is what most third-party setup guides still describe. The server remains in beta and HubSpot advises experimenting in a developer sandbox and reviewing every write confirmation, since an LLM will occasionally propose a change to a system of record that it should not.

The official MongoDB MCP server, `mongodb-js/mongodb-mcp-server`, maintained by MongoDB. Searchers find it as the MongoDB MCP server or the Mongo MCP server; both names refer to this one project, and there is no separate short-form server. It is really two tool surfaces in one process. The database tools connect to any MongoDB deployment over a connection string in `MDB_MCP_CONNECTION_STRING` — `find`, `aggregate`, `explain`, `collection-schema`, `collection-indexes`, `create-index`, `count`, `export`, `mongodb-logs` and the write tools — or, if no connection string is set, the model calls the `connect` tool at runtime and passes the returned `connectionId` to later calls. The Atlas tools are a separate control plane: listing and creating clusters, database users, IP access-list entries, stream processing resources and the performance advisor. They authenticate with Atlas Service Account credentials (`MDB_MCP_API_CLIENT_ID` / `MDB_MCP_API_CLIENT_SECRET`), not with a connection string, and they simply do not register when those are unset — the usual cause of a 'the Atlas tools are missing' report. Two defaults are worth knowing before you point it at production. `readOnly` is false, so every write tool including `drop-database` is registered unless you pass `--readOnly`, which is why MongoDB's own README uses that flag in every example. And confirmation-required tools rely on MCP elicitation, so on a client that does not support elicitation they execute without prompting — `--readOnly` or `--disabledTools` is the actual boundary. Other guardrails: `indexCheck` rejects queries that would do a collection scan, server-side JavaScript (`$where`, `$function`, `$accumulator`) is disabled by default, results are capped at 100 documents and 16 MB per call, and `--dryRun` prints the resolved config and enabled tool list without starting the server. Requires Node 22.13.0 or later (Node 20 is deprecated); also published as the `mongodb/mongodb-mcp-server` Docker image. Runs over stdio by default, with an optional HTTP transport and a separate monitoring listener for `/health` and Prometheus `/metrics`.

Agent-driven builds, simulator runs, tests and debugging for iOS and macOS projects, by wrapping xcodebuild, simctl and the device tooling behind MCP. The project is XcodeBuildMCP, and the first thing to know about it is that it moved: the repository that most write-ups still link, `cameroncooke/XcodeBuildMCP`, now redirects to `getsentry/XcodeBuildMCP` — Sentry took stewardship, and the canonical package, docs site and Homebrew tap all live under that org. At 6,172 stars it is the most-adopted Xcode MCP server by a wide margin. It ships as one package with two modes off the same install: an MCP server for agents (`xcodebuildmcp mcp`, or on demand via `npx -y xcodebuildmcp@latest mcp` with no global install) and a plain CLI for terminal use (`xcodebuildmcp simulator build --scheme MyApp --project-path ./MyApp.xcodeproj`, `xcodebuildmcp tools`, `xcodebuildmcp upgrade --check`). Install with Homebrew (`brew tap getsentry/xcodebuildmcp && brew install xcodebuildmcp`) or npm (`npm install -g xcodebuildmcp@latest`); Homebrew is the path that does not require Node. Beyond build-and-run it covers the workflow steps agents usually cannot reach — booting and driving simulators, capturing logs through a per-workspace daemon that auto-starts for stateful operations, and splitting test builds from test runs via `--build-for-testing` and a portable `.xctestproducts` bundle so a prepared build can be executed later against a named simulator. It also installs optional agent Skills (`xcodebuildmcp init`) that prime the model on the tool surface — recommended for the CLI mode in particular. Requirements are strict and worth checking before you file a bug: macOS 14.5+, Xcode 16.x+, and Node 18+ unless you installed through Homebrew. Two behaviours to know up front: it asks xcodebuild to skip macro validation so Swift Macros projects do not fail the build, and device (as opposed to simulator) tools need code signing already configured in Xcode. Sentry is used for runtime error telemetry only, with documented opt-out. MIT licensed, TypeScript, actively maintained.

The PostgreSQL MCP server was the Model Context Protocol reference server for Postgres, and it is retired: the source now sits in modelcontextprotocol/servers-archived — a repository GitHub reports as archived, described as "Reference MCP servers that are no longer maintained" — and the npm package @modelcontextprotocol/server-postgres carries a deprecation notice reading "Package no longer supported." It still installs and still runs, which is why most third-party setup articles have not caught up. What it provides is deliberately small: a single tool, query, which executes read-only SQL inside a READ ONLY transaction, plus per-table schema information exposed as MCP resources at postgres://<host>/<table>/schema, with column names and data types discovered from database metadata. There is no index advice, no health check, no separate schema-listing tool, and no write mode. Install is npx @modelcontextprotocol/server-postgres with a postgres:// connection string as the argument. For active work against Postgres, the maintained alternative is Postgres MCP Pro (crystaldba/postgres-mcp), which exposes nine tools including index tuning against hypothetical indexes and a database health check, and has an explicit restricted access mode; if your database is hosted on Supabase or Neon, their platform servers add branching and logs that a raw Postgres connection cannot see. Reach for this archived server only when you want the smallest possible surface — one process, one read-only query tool, nothing else.

conversational read and write access to any SQLite database file, plus a running business-insights memo that accumulates what the analysis turns up. It is a Python server on PyPI, not a Node one, and the difference is the single most common reason setups fail here: `@modelcontextprotocol/server-sqlite` does not exist on npm, so every npx line for it 404s. The working invocation is `uvx mcp-server-sqlite --db-path /path/to/database.db` (PyPI package mcp-server-sqlite, v2025.4.25), or the equivalent `mcp/sqlite` Docker image with a volume mounted at /mcp. The --db-path argument is required and points at the .db file; the server will create it if it is not there yet. Six tools are exposed, deliberately split by risk: read_query for SELECT only, write_query for INSERT/UPDATE/DELETE, create_table for DDL, list_tables and describe-table for schema introspection, and append_insight, which writes into a memo://insights resource that updates live as findings accumulate — that resource, not the SQL tools, is what makes this server different from a generic database connector. It also ships an mcp-demo prompt that takes a business topic, generates a plausible schema and sample data, and walks through an analysis end to end, which is the fastest way to see the memo behaviour without wiring up real data. One caveat to weigh before adopting it: this is an Anthropic reference implementation that now lives in modelcontextprotocol/servers-archived, archived on 2025-05-28. The published package still installs and runs, but it is frozen — no new features, no dependency updates, and no security patches.

The Redis MCP Server (redis/mcp-redis) is Redis's own natural-language interface for agentic applications, letting an AI client read and write Redis data over the Model Context Protocol. Note which one you install: the server most tutorials still point at is Anthropic's reference implementation, which now lives in modelcontextprotocol/servers-archived, and its npm package @modelcontextprotocol/server-redis is explicitly marked "Package no longer supported" with a last publish of 2025-04-25. The maintained server is a Python package instead, run with uvx --from redis-mcp-server@latest, and it covers far more of Redis than the reference one did: string, hash, list, set and sorted-set tools; JSON document tools; pub/sub with stateful channel and pattern subscriptions; Streams tools including consumer-group create, read, acknowledge and destroy; vector index management and vector search through the query engine; a docs search tool; and a server-management tool for database info. Connection is a redis:// or rediss:// URL passed as --url, or the REDIS_HOST/REDIS_PORT/REDIS_PWD/REDIS_SSL environment variables, with Redis Cluster mode behind REDIS_CLUSTER_MODE and EntraID service-principal, managed-identity and default-credential auth flows for Azure Managed Redis. There is no --read-only flag: the documented way to stop an agent writing is a Redis ACL user (ACL SETUSER readonlyuser on >pw ~* +@read -@write). Ships as a PyPI package, a GitHub install via uvx, and an official mcp/redis Docker image; stdio transport only.
