agentic-mcp-server-builder

agentic-mcp-server-builder is a skill for Codex from 0x-Professor/Agent-Skills-Hub. It costs 35 tokens per session (178 once invoked), scanned A, original, Apache-2.0.

A starter-project generator for MCP servers. MCP is a standard way for an AI system to connect to tools with defined inputs and outputs.

In plain words
What is it for?
Use it to define tool schemas, create an MCP server scaffold, list starter files, and check that the server structure is ready for implementation.
Why use it?
It gives tool contracts and a consistent project layout before business logic is added, reducing unclear tool boundaries and interface mistakes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentic-mcp-server-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scaffold_mcp_server.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Agentic MCP Server Builder

Overview

Create a minimal MCP server scaffold and contract summary from a structured tool list.

Workflow

  1. Define server name and tool list with descriptions.
  2. Generate scaffold file map and tool contract summary.
  3. Optionally materialize starter files when not in dry-run mode.
  4. Review generated contract checks before adding business logic.

Use Bundled Resources

  • Run scripts/scaffold_mcp_server.py to generate starter artifacts.
  • Read references/mcp-scaffold-guide.md for file layout and contract checks.

Guardrails

  • Keep tool boundaries explicit and minimal.
  • Include deterministic outputs and clear input/output schemas.
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
