configure-mcp

configure-mcp is a skill for Claude Code, Codex from soulcodex/agentic. It costs 68 tokens per session (630 once invoked), scanned A, original, MIT.

A guide for setting up MCP, a standard way for an AI agent to connect to outside tools and services. It recommends suitable servers for a project and guides you through adding one.

In plain words
What is it for?
Use it when connecting an agent to GitHub, files, PostgreSQL databases, live library documentation, or browser automation.
Why use it?
It helps you choose the right connection instead of guessing which server or setup steps you need. It also provides a fallback approach for GitHub issue-backed plans when MCP is unavailable.

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

configure-mcp 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 5d ago.

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.

Configure MCP Skill

Guide the user through selecting and configuring an MCP server for their project. For GitHub issue planning workflows, MCP is the preferred path for issue-backed plan persistence. If MCP is unavailable or misconfigured, use gh CLI as the primary fallback.

Step 1 — Understand the Stack

Ask the user:

  • What language and framework is the project using?
  • What external services or data sources does it interact with? (GitHub, databases, browser automation, documentation lookup, etc.)
  • What tasks should the AI agent be able to help with?

Step 2 — Recommend Servers

Based on the stack, recommend from the canonical short-list:

Server When to use it
github GitHub repos, issues, PRs, CI status
filesystem Direct file system access within a bounded path
postgres Query and inspect a PostgreSQL database
context7 Live documentation lookup for libraries and frameworks
playwright Browser automation and end-to-end testing

Explain which servers apply to the user's project and why.

Step 3 — Run the Wizard

Tell the user to run the interactive wizard:

just mcp-add /path/to/project

Walk them through the prompts:

  1. Enter the server name (e.g. github)
  2. Choose transport: stdio for local executables, http for remote servers
  3. Enter the command (e.g. npx -y @modelcontextprotocol/server-github)
  4. Add environment variables (e.g. GITHUB_TOKEN)
  5. Confirm the write to .mcp.json 6. Optionally sync to .gemini/settings.json

Step 4 — Verify

After the wizard completes, verify with:

just mcp-list /path/to/project

This should show the newly configured server in the table.

Step 5 — Environment Setup

Remind the user: environment variables referenced in the MCP config (e.g. ${GITHUB_TOKEN}) must be set in the shell before starting the AI tool. They are not stored in .mcp.json — only the variable references are.

Add them to the project's .env or the system environment as appropriate.

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.

configure-mcp is a skill published in the GitHub repository soulcodex/agentic (10 stars, last pushed yesterday), licensed MIT. It adds 68 tokens to every session and 630 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
