mcp

mcp is a cursor rule for Cursor from mehmetfiskindal/cursor-pro-limits-mcp. It costs 192 tokens per session, scanned A, original, MIT.

A set of coding rules for building MCP servers in TypeScript. MCP, or Model Context Protocol, is a way for AI applications to connect to tools and data sources.

In plain words
What is it for?
Developing MCP tools and handlers, defining TypeScript interfaces, enforcing linting and formatting, documenting code, and organising source files and examples.
Why use it?
It gives a project consistent expectations for types, validation, error handling, formatting, documentation, and file organisation. This helps prevent loosely typed or poorly structured server code.

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.

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

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.

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.
