api-services

Reference material for built-in services used by MCP servers, including language models, speech recognition and text-to-speech, and relationship graphs. It documents the interfaces and integration patterns for those services.

In plain words
What is it for?
Use it when adding or accessing an LLM, speech service, or graph provider in an MCP server.
Why use it?
It gives developers one place to check how these service providers work instead of guessing their interfaces or setup steps.

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

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 2d 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.

Origin

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.

References

Reference Path Description
LLM references/llm.md OpenRouter-based LLM provider (ILlmProvider, streaming, config)
Speech references/speech.md TTS/STT providers (SpeechService, ElevenLabs, Whisper)
Graph references/graph.md Relationship graph operations (IGraphProvider, traversal, pathfinding)
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.
