MCP Development
MCP Server with Tools
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
const server = new McpServer({
name: "project-tools",
version: "1.0.0",
});
server.tool(
"search_files",
"Search for files matching a glob pattern in the project directory",
{
pattern: z.string().describe("Glob pattern (e.g., '**/*.ts')"),
directory: z.string().optional().describe("Base directory to search from"),
},
async ({ pattern, directory }) => {
const files = await glob(pattern, { cwd: directory ?? process.cwd() });
return {
content: [
{
type: "text",
text: files.length > 0
? files.join("\n")
: `No files found matching ${pattern}`,
},
],
};
}
);
server.tool(
"run_query",
"Execute a read-only SQL query against the application database",
{
query: z.string().describe("SQL SELECT query to execute"),
limit: z.number().default(100).describe("Maximum rows to return"),
},
async ({ query, limit }) => {
if (!query.trim().toUpperCase().startsWith("SELECT")) {
return {
content: [{ type: "text", text: "Only SELECT queries are allowed" }],
isError: true,
};
}
const rows = await db.query(`${query} LIMIT ${limit}`);
return {
content: [{ type: "text", text: JSON.stringify(rows, null, 2) }],
};
}
);
Resources
server.resource(
"schema",
"db://schema",
"Current database schema with all tables, columns, and relationships",
async () => {
const schema = await db.query(`
SELECT table_name, column_name, data_type, is_nullable
FROM information_schema.columns
WHERE table_schema = 'public'
ORDER BY table_name, ordinal_position
`);
return {
contents: [
{
uri: "db://schema",
mimeType: "application/json",
text: JSON.stringify(schema, null, 2),
},
],
};
}
);
server.resource(
"config",
"config://app",
"Application configuration (secrets redacted)",
async () => {
const config = await loadConfig();
const safe = redactSecrets(config);
return {
contents: [
{
uri: "config://app",
mimeType: "application/json",
text: JSON.stringify(safe, null, 2),
},
],
};
}
);
Prompt Templates
server.prompt(
"review-code",
"Review code changes for bugs, security issues, and style",
{
diff: z.string().describe("Git diff or code to review"),
focus: z.enum(["security", "performance", "style", "all"]).default("all"),
},
async ({ diff, focus }) => ({
messages: [
{
role: "user",
content: {
type: "text",
text: `Review this code diff. Focus: ${focus}\n\n${diff}`,
},
},
],
})
);
Client Configuration
{
"mcpServers": {
"project-tools": {
"command": "node",
"args": ["./mcp-server/dist/index.js"],
"env": {
"DATABASE_URL": "postgres://localhost:5432/app"
}
},
"remote-server": {
"url": "https://mcp.example.com/sse",
"headers": {
"Authorization": "Bearer ${MCP_TOKEN}"
}
}
}
}
Transport Setup
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
const transport = new StdioServerTransport();
await server.connect(transport);
For HTTP-based servers, use the SSE transport for streaming responses to clients.
Anti-Patterns
- Creating tools with vague descriptions that don't explain when to use them
- Not validating inputs with Zod schemas before processing
- Returning raw error stack traces to the client
- Missing
isError: trueflag on error responses - Creating too many fine-grained tools instead of composable ones
- Not redacting secrets in resource responses
Checklist
- Each tool has a clear description explaining when and why to use it
- Input parameters validated with Zod schemas and descriptive messages
- Error responses include
isError: truewith user-friendly messages - Resources expose read-only data with secrets redacted
- Prompt templates provide structured starting points for common tasks
- Server handles graceful shutdown on SIGINT/SIGTERM
- Tools are composable (do one thing well) rather than monolithic
- Client configuration documented with required environment variables
FAQ
What does the mcp-development skill do?
MCP server development including tool design, resource endpoints, prompt templates, and transport configuration
How do I install mcp-development?
Run npx skills add https://github.com/rohitg00/awesome-claude-code-toolkit --skill mcp-development in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/mcp-development/ (personal) or .claude/skills/mcp-development/ (project).
Which AI agents can use mcp-development?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is mcp-development safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains mcp-development?

Popular ai & agents skills
google-agents-cli-publish
google/agents-cli
This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).
google-agents-cli-eval
google/agents-cli
This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).
skill-creator
anthropics/skills
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
