Claude Code Settings Configuration
stdio Transport (Most Common)
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/directory"]
},
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_TOKEN}"
}
},
"postgres": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-postgres"],
"env": {
"POSTGRES_URL": "${DATABASE_URL}"
}
}
}
}
SSE Transport (HTTP-based)
{
"mcpServers": {
"remote-server": {
"type": "sse",
"url": "https://your-mcp-server.example.com/sse",
"headers": {
"Authorization": "Bearer ${API_TOKEN}"
}
}
}
}
Environment Variable Injection Pattern
Never hardcode credentials in settings.json. Use environment variable references:
{
"env": {
"API_KEY": "${MY_SERVICE_API_KEY}"
}
}
Variables are resolved from the shell environment where Claude Code runs.
Agent Studio MCP Integration
Agent Studio skills that wrap MCP servers:
| Skill | Underlying MCP | Agent Studio Path |
| ---------------------- | ------------------------------------- | -------------------------------------- |
| github-ops | @modelcontextprotocol/server-github | .claude/skills/github-ops/ |
| github-mcp | @modelcontextprotocol/server-github | .claude/skills/github-mcp/ |
| figma | Figma MCP server | .claude/skills/figma/ |
| google-workspace | Google Drive + Sheets MCP | .claude/skills/google-workspace/ |
| slack-notifications | Slack MCP | .claude/skills/slack-notifications/ |
| linear-pm | Linear MCP | .claude/skills/linear-pm/ |
| jira-pm | Jira MCP | .claude/skills/jira-pm/ |
| arxiv-mcp | ArXiv search | .claude/skills/arxiv-mcp/ |
| webmcp-browser-tools | Browser tools MCP | .claude/skills/webmcp-browser-tools/ |
Adding a New MCP Server
Step 1: Identify the Server
# Search npm registry
npm search "@modelcontextprotocol/server-"
# Browse community list
# https://github.com/modelcontextprotocol/servers
Step 2: Configure in settings.json
Edit .claude/settings.json to add the mcpServers entry (see templates above).
Step 3: Test the Connection
# Verify Claude Code loads the MCP server
claude --mcp-debug
Step 4: Create an Agent Studio Skill (Optional)
If the MCP server is used frequently, wrap it in an Agent Studio skill:
# Use the skill-creator skill
Skill({ skill: 'skill-creator' })
The skill should:
- Document the MCP server's tools and resources
- Provide usage examples
- Define when to invoke
- List required environment variables
Security Considerations
Credential Management
- Store all secrets in
.env(never insettings.jsondirectly) - Use
${ENV_VAR}interpolation in settings.json - Rotate tokens regularly; use minimal-scope PATs
File System Access
- Restrict
filesystemserver to specific directories only - Never grant root (
/) or home (~) access - Use read-only mode when write access is not needed
Network MCP Servers
- Validate SSL certificates on SSE connections
- Use bearer token auth for remote MCP servers
- Audit tool calls from remote servers — treat as untrusted input
Least Privilege
- Only register MCP servers that the agent actually needs
- Remove unused MCP server registrations
- Prefer local stdio over remote SSE when possible
MCP Protocol Reference
Tool vs Resource vs Prompt
| Concept | Purpose | Agent Interaction |
| ------------ | -------------------------------------- | -------------------------------------------- |
| Tool | Execute actions (write file, call API) | Agent calls mcp__serverName__toolName() |
| Resource | Read data (file contents, DB records) | Agent reads mcp://serverName/resource/path |
| Prompt | Reusable prompt templates | Agent requests prompt template by name |
Naming Convention in Claude Code
MCP tools appear as: mcp__<serverName>__<toolName>
Example: mcp__github__create_issue, mcp__filesystem__read_file
Discovery
To list all available MCP tools in a session:
// Agents can discover available MCP tools via AvailableAgents() or tool search
Skill({ skill: 'tool-search' });
