Best MCP Servers for Claude Code — Hand-Curated 2026 List
Hundreds of MCP servers exist. Most of them are demos that solved their own author's problem once and were never touched again. These are the ones we keep installed across every Claude Code project.
## Selection criteria
- Solves a recurring problem we hit weekly
- Doesn't crash Claude Code
- Active maintenance in 2026
- Either zero-config or trivial-config setup
## The list
### 1. `@modelcontextprotocol/server-filesystem`
The single most useful MCP server. Sandboxed file access to specific directories outside the current repo. Use case: Claude Code coordinating between client project and your personal toolbox in `~/Tools/`.
### 2. `@modelcontextprotocol/server-git`
Structured git access. Better than raw Bash for blame, diff, and rebase operations.
### 3. `mcp-omnisearch`
Bundles Brave, Tavily, Exa, Perplexity. Drop your API keys in once, Claude picks the right search engine per query with auto-fallback.
### 4. `mcp-server-time`
Sounds trivial. Isn't. Claude often gets dates wrong when the conversation has been going for hours. Adding time-server stops most hallucinated "as of November 2024..." comments that should say 2026.
### 5. `mcp-server-postgres`
Schema introspection + read-only query execution. Far better than letting Claude guess at column names from old migrations.
## What we removed
We've tried 40+ MCP servers and uninstalled most. Common reasons:
- Sluggish startup (slow MCP servers slow down every Claude Code session)
- Permission scope too wide
- Bug-ridden / unmaintained
- Duplicates built-in tools without adding value
