GitHub

Why it matters

Reference filesystem access remains a core MCP security surface because agents can read, write, search, and move local files when configured.

Sentry MCP

Developer debugging MCP

Public-source checked

Website GitHub

Why it matters

Brings Sentry debugging context into coding assistants, creating clear overlap with developer workflows, observability, and human-in-the-loop agent operations.

Cloudflare MCP Server

Cloud infrastructure MCP

Public-source checked

GitHub

Why it matters

Lets MCP clients interact with Cloudflare services, which makes identity, permissions, and infrastructure-change review especially important.

Atlassian Rovo MCP Server

Enterprise knowledge MCP

Public-source checked

Website GitHub

Why it matters

Connects agents to Jira, Confluence, and Compass data, making it relevant for enterprise knowledge access and governance research.

Postgres MCP Pro

Database MCP

Public-source checked

GitHub

Why it matters

Database-facing MCP servers are high-signal for access control, query review, data exposure, and agentic database operation risks.

Slack MCP Server

Collaboration MCP

Needs verification for current status

GitHub

Why it matters

Chat and collaboration connectors are useful to monitor because they expose team context and workflow actions to assistants.

Fetch MCP Server

Web retrieval MCP

Needs verification for current status

GitHub

Why it matters

Web-fetching tools shape how agents retrieve external content, making them relevant for source trust, prompt injection, and browsing policy research.

Research boundary

Public-source research, not a private contact database

This directory is based on public websites, documentation, GitHub repositories, and public product pages. It is meant for research and market mapping, not automated outreach.

Manual verification

Manually verify before outreach

Categories and URLs can change. Before using any project for sales, partnership, investment, or security research, review the current public source and confirm the contact angle is accurate.
