MCP servers directory

Standalone servers speaking the Model Context Protocol. stdio for local agents, SSE for remote ones. Listed alphabetically — this is a directory, not a ranking. Sample entries shown.

Server	Description	Transport	Version	Category
calendar-bridge	Read and propose calendar events with conflict detection. Proposals never write without confirmation.	stdio	v0.8.1	productivity
db-bridge	Read-only SQL execution against Postgres/MySQL with query guardrails and row limits.	stdio	v2.0.3	data
doc-extract	PDF and Office document extraction: text blocks, tables, and page citations.	stdio	v1.4.2	documents
email-agent	Triage, draft, and label email. Drafts stay drafts until a human approves.	SSE	v1.2.0	productivity
fs-tools	Scoped file read/write, search, and patch operations for agent sandboxes.	stdio	v1.6.0	devtools
git-helper	Branch, diff, and PR workflows with conventional-commit message generation.	stdio	v1.1.4	devtools
translate-svc	Glossary-aware translation endpoint with terminology locking per project.	SSE	v1.1.3	language
webfetch	Fetch and clean web content to markdown with redirect and robots handling.	SSE	v0.9.2	web

Wiring a server into your agent

# example client config (stdio transport)
{
  "mcpServers": {
    "fs-tools": {
      "command": "npx",
      "args": ["-y", "@skillbank/mcp-fs-tools@1.6.0"],
      "env": { "FS_ROOT": "/workspace" }
    }
  }
}

tipPin the server version in your client config the same way you pin skills. @1.6.0 today means @1.6.0 next quarter.

Transports, briefly

⌁

stdio

The server runs as a child process of your agent and talks over stdin/stdout. Lowest latency, local only.

≈

SSE

The server runs remotely and streams events over HTTP. Reachable from anywhere, needs auth.
