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 | $0.00032 | $0.00231 |
| Opus 5 | $0.00016 | $0.00115 |
| Sonnet 5 | $0.00006 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
api-services 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 4d 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.
This is a copy
100% identical to api-services — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Overview
Service providers are exported from @cyanheads/mcp-ts-core/services. These are documented here for servers that use the built-in providers.
All services follow the init/accessor pattern: initialized in setup(), accessed at request time via lazy accessor. See the add-service skill for the full pattern.

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.
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.

api-services is a skill published in the GitHub repository cyanheads/toolkit-mcp-server (18 stars, last pushed 12d ago), licensed Apache-2.0. It adds 32 tokens to every session and 231 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to api-services, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
build-mcp-server
This skill should be used when the user asks to "build an MCP server", "create an MCP", "make an MCP integration", "wrap an API for Claude", "expose tools to Claude", "make an MCP app", or discusses building something with the Model Context Protocol. It is the entry point for MCP server development — it interrogates…
implementation-strategy
Decide how to implement runtime and API changes before editing code. Use when a task changes exported APIs, MCP tool definitions, runtime behavior, or configuration, and you need to choose the compatibility boundary and implementation shape.
docs-sync
Audit documentation coverage by comparing implementation against docs/. Use when asked to check doc coverage, sync docs with code, or after significant API surface changes. Produce a report and ask for approval before editing.
pr-draft-summary
Generate a PR-ready summary block with branch suggestion, title, and description. Use in the final handoff after moderate-or-larger code changes; skip for trivial or conversation-only tasks.
code-change-verification
Run the verification stack (format, lint, typecheck, test) when changes affect runtime code, tests, or build config.
typescript
This skill should be used when the user asks to "optimize TypeScript performance", "speed up tsc compilation", "configure tsconfig.json", "fix type errors", "improve async patterns", or encounters TS errors (TS2322, TS2339, "is not assignable to"). Also triggers on .ts, .tsx, .d.ts file work involving type…
