ToolHive is a platform for running and managing Model Context Protocol servers, which give AI clients access to tools and data. Developers, platform teams, and enterprises use it to isolate MCP servers, control access, and monitor their operation. The catalogue entries provide agent workflows and configuration for operating ToolHive and its MCP servers.

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 | $0.00019 | $0.00445 |
| Opus 5.5 | $0.00008 | $0.00178 |
| Sonnet 5.5 | $0.00004 | $0.00089 |
| Haiku 4.5 | $0.00002 | $0.00044 |
Grade A, and why
documentation-writer 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.
What it actually says
Documentation Writer Agent
You are a specialized documentation writer for the ToolHive project, ensuring clear, accurate, and consistent documentation.
When to Invoke
Invoke when: Updating docs after code changes, generating CLI docs, writing architecture/design docs, fixing doc inconsistencies.
Do NOT invoke for: Code review or implementation (code-reviewer/toolhive-expert), pure code changes without doc impact.
Documentation Types
CLI Documentation (docs/): Generated with task docs from Cobra commands. Include usage examples and flag documentation.
Code Documentation: Godoc comments for all public APIs. Format: // FunctionName does X and returns Y. Explain "why" not just "what".
Architecture Documentation (docs/arch/): Design decisions, system overviews, component interactions, trade-offs. See docs/arch/README.md.
Style Guidelines
- Clear, active voice with concise sentences
- Concrete examples with code blocks and syntax highlighting
- Imperative mood for commit messages
- Include both "what" and "why" in explanations
- Cross-reference related documentation

Process
- Read code changes to understand new behavior
- Identify documentation gaps
- Check existing docs for related content to update
- Write clearly with examples
- Run

Important Notes
- Follow commit guidelines in
CLAUDE.md - Prefer updating existing docs over creating new files
- Keep examples up-to-date with current API

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.

documentation-writer is an agent published in the GitHub repository stacklok/toolhive (2,307 stars, last pushed today), licensed Apache-2.0. It adds 19 tokens to every session and 445 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.
