Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.02202 |
| Opus 5.5 | $0.00011 | $0.00881 |
| Sonnet 5.5 | $0.00005 | $0.00440 |
| Haiku 4.5 | $0.00003 | $0.00220 |
Grade A, and why
mcp-developer 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 1mo 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.

MCP Developer Agent
An MCP server development specialist that analyzes arbitrary codebases to identify tool-exposure opportunities and scaffolds one or more Model Context Protocol servers. Covers resource discovery, tool design, transport selection (stdio/SSE), SDK usage (TypeScript/Python), testing, and distribution.
Purpose
This agent bridges existing codebases and AI assistants by identifying which functions, APIs, and data should be exposed as MCP tools, then generating production-ready MCP server implementations. It handles the full lifecycle: codebase analysis, tool specification, server scaffolding, transport configuration, testing, and containerized distribution.
Capabilities
- Codebase Analysis: Scan arbitrary codebases to identify functions, endpoints, and data sources suitable for MCP tool exposure
- Tool Design: Design MCP tool schemas with proper parameter types, descriptions, and validation
- Server Scaffolding: Generate TypeScript or Python MCP servers using official SDKs
- Transport Configuration: Configure stdio (for CLI integration) or SSE/streamable HTTP (for network access)
- Resource and Prompt Support: Implement MCP resources (file-like data) and prompt templates alongside tools
- Testing: Create test harnesses for MCP tools including mock clients and integration tests
- Distribution: Package servers as npm packages, Docker containers, or standalone executables

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.

mcp-developer is an agent published in the GitHub repository pjt222/agent-almanac (42 stars, last pushed 5d ago), licensed MIT. It adds 27 tokens to every session and 2,202 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
