a single structured-reasoning tool that lets a model plan, revise and branch its own chain of thought instead of answering in one shot. Published by Anthropic as part of the official modelcontextprotocol/servers monorepo (89,000+ stars, actively maintained), it exposes exactly one tool — sequential_thinking — and that tool is the whole product. Each call carries a `thought` string plus bookkeeping fields: `thoughtNumber`, `totalThoughts`, and `nextThoughtNeeded`, which the model flips to false when it is done. The interesting fields are the optional ones. `isRevision` and `revisesThought` let the model go back and correct an earlier step rather than plowing ahead on a bad assumption; `branchFromThought` and `branchId` let it fork into an alternative line of reasoning and carry both forward; `needsMoreThoughts` lets it extend past its own original estimate when a problem turns out to be deeper than it looked. In practice you never call the tool by hand. You connect the server to an MCP host and ask a question that deserves more than one pass — plan a PostgreSQL 14 to 16 migration and revise if downtime exceeds five minutes, work out why a deploy only fails in production, compare three architectures and branch when an assumption breaks. You can tell it is working when the host inspector shows repeated sequential_thinking calls with a rising `thoughtNumber` rather than a single response. Install with `npx -y @modelcontextprotocol/server-sequential-thinking` — note the hyphenated package name, which differs from both the `sequentialthinking` directory in the repo and the Docker image `mcp/sequentialthinking`, a mismatch that breaks a lot of copied configs. A Docker image is published alongside the npm package, and the README carries one-click VS Code install buttons for both transports. Set `DISABLE_THOUGHT_LOGGING=true` if you do not want every thought written to the server log.

authenticated access to the whole GitHub platform — repositories, files, branches, issues, pull requests, Actions runs, security alerts, discussions and notifications — from Claude, Cursor, VS Code, Copilot CLI and any other MCP host. There is no npm package for this server, and that trips up most people who try to install it: `@github/mcp-server` is not published to the npm registry, so any `npx` line you find for it will fail. GitHub ships it three other ways. The easiest is the hosted remote server at https://api.githubcopilot.com/mcp/, which needs no install at all — point an HTTP-transport MCP client at that URL and log in with OAuth (VS Code 1.101+, Claude Desktop, Claude Code, Cursor and Windsurf all support this). The second is the official Docker image ghcr.io/github/github-mcp-server, which is what the copy-paste command on this page runs; on github.com it now performs a browser-based OAuth login on first use and keeps the token in memory only, which is why the published Docker configs map a fixed loopback callback port (-p 127.0.0.1:8085:8085 with GITHUB_OAUTH_CALLBACK_PORT=8085) so the container can receive the callback. Prefer a token? Set GITHUB_PERSONAL_ACCESS_TOKEN instead — it takes precedence over OAuth, and the minimum useful scopes are repo, read:org and read:packages. The third is the native Go binary from the repository's releases, which needs no fixed port for the OAuth flow. GitHub Enterprise Server has no hosted option: use the local server with --gh-host or GITHUB_HOST set to your instance (include the https:// scheme — it defaults to http://, which GHES rejects). Toolsets can be narrowed with GITHUB_TOOLSETS, and an insiders channel is available at /mcp/insiders or via the X-MCP-Insiders header.

a first-party MCP endpoint built into the GitLab instance itself — there is no package to install, because the server ships inside GitLab and answers at https://<your-gitlab>/api/v4/mcp (gitlab.com exposes the same path, so https://gitlab.com/api/v4/mcp works for SaaS projects). It landed as an experiment in GitLab 18.3 and moved to beta in 18.6. Authentication is the part that makes it different from every community GitLab server: it uses OAuth 2.0 Dynamic Client Registration, so the first time a client connects it registers itself as an OAuth application on your instance and is issued an access token — no personal access token pasted into a config file. Administrators who do not want one OAuth application per tool can pre-create a shared application instead. Three prerequisites are what actually block most first connections: GitLab Duo must be set to Always on or On by default, beta and experimental features must be enabled, and MCP access must be switched on at the group or instance level. The tool surface covers issues and merge requests (create_issue, get_issue, create_merge_request, get_merge_request, list_merge_requests, get_merge_request_commits, get_merge_request_diffs, get_merge_request_pipelines, create_merge_request_note, get_merge_request_notes), CI/CD (manage_pipeline for list/create/delete/retry/cancel, get_pipeline_jobs, get_job_log), work items (create_workitem_note, get_workitem_notes, link_work_items, get_saved_view_work_items), search (search across the instance, search_labels, semantic_code_search), list_wiki_pages, and attach_scan_profile. HTTP is the recommended transport — claude mcp add --transport http GitLab https://gitlab.com/api/v4/mcp — and clients that only speak stdio can wrap it with npx mcp-remote <url> on Node 20+. Send the X-Gitlab-Mcp-Server-Tool-Name-Prefix header if generic names like search collide with another connected server. If your instance predates 18.3 or Duo is not available to you, the community alternative most teams land on is zereight/gitlab-mcp (1,889 stars as of 2026-08-16, npm @zereight/mcp-gitlab), which authenticates with a plain personal access token and ships 217 tools — including merge_merge_request, approve_merge_request, execute_graphql and full CI/CD variable management, none of which the built-in server exposes — behind GITLAB_PERMISSION_MODE=readonly/modify and GITLAB_TOOLSETS/GITLAB_TOOLS filtering. One further change worth noting: MCP server access moved from GitLab Premium to GitLab Free in 19.2 and became a setting of its own.

The MCP server is free. GitLab: Free tier with 5 users. Premium: $29/user/mo. Ultimate: $99/user/mo.

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 MCP server is free and open-source. Notion: Free for personal use. Plus: $10/user/mo. Business: $18/user/mo. Enterprise: Custom pricing.

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 MCP server is free. Linear: Free tier for small teams. Standard: $8/user/mo. Plus: $14/user/mo. Enterprise: Custom pricing.

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 MCP server is free and open-source. HubSpot CRM: Free tier available. Starter: $20/mo. Professional: $890/mo. Enterprise: $3,600/mo.
