What MCP servers does
According to its repository: “MCP server for Gmail with OAuth2 (personal) and service account (Workspace) support.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. MCP servers is listed under Messaging and email, a category of 107 servers in the directory, where it ranks #31 by stars.
Installing and connecting MCP servers
Distribution modes declared in the official MCP registry:
- npm package (Node.js, usually started with
npx)
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.
The registry lists 5 secret variables to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
Points found for MCP servers:
- Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on May 12, 2025, the pulsemcp/mcp-servers repository has 81 stars and 10 forks, with 26 open issues. It has more stars than 62% of the servers in the directory. It received changes this month. Version published in the registry: 0.4.12 (August 30, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
