Configure and build Model Context Protocol (MCP) servers for Claude Code integration. Set up database, filesystem, git, and API connections. Build custom MCP servers with TypeScript/Python SDK, implement tools and resources, configure transports (stdio, HTTP), and deploy for production.

Claude Code MCP

Specification: https://modelcontextprotocol.io/specification/2025-11-25 (November 2025)

Use this skill when you need to:

Configure
```
.claude/.mcp.json
```
for official/community MCP servers
Build custom MCP servers (TypeScript or Python)
Deploy and harden remote MCP servers (HTTP transport)

Quick Start (Local stdio via npx)

Create or edit
```
.claude/.mcp.json
```
:

{
  "mcpServers": {
    "postgres": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-postgres"],
      "env": { "POSTGRES_URL": "${DATABASE_URL}" }
    }
  }
}

Provide env vars and validate the connection:

export DATABASE_URL="postgresql://user:pass@localhost:5432/db"
claude mcp list
claude mcp get postgres

Notes:

Default config path is typically
```
.claude/.mcp.json
```
. If needed, override via
```
claude --mcp-config <path>
```
.
Prefer
```
python3
```
as the Python interpreter in server configs unless your environment guarantees
```
python
```
.

Permission Management (Recommended)

# Allow all tools from a server (wildcard)
claude mcp add --allow "mcp__postgres__*" postgres -- npx -y @modelcontextprotocol/server-postgres

# Allow specific tools only
claude mcp add --allow "mcp__postgres__query,mcp__postgres__list_tables" postgres -- npx -y @modelcontextprotocol/server-postgres

# Deny a specific tool
claude mcp add --deny "mcp__filesystem__write_file" filesystem -- npx -y @modelcontextprotocol/server-filesystem ./data

Production Guardrails (Required)

Assume tool outputs are untrusted (prompt injection). Sanitize/structure before reuse.
Default to least privilege: read-only DB, scoped filesystem allowlists, minimal tool allowlists.
Keep secrets out of
```
.mcp.json
```
; inject via env vars or a secret manager at runtime.
Add timeouts, retries, and rate limits; log all tool invocations for audit.
