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 | $0.00051 | $0.01054 |
| Opus 5 | $0.00026 | $0.00527 |
| Sonnet 5 | $0.00010 | $0.00211 |
| Haiku 4.5 | $0.00005 | $0.00105 |
Grade A, and why
abs-mcp-comparison 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 9d 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.

ABS MCP Comparison
Purpose
Keep the README comparison against other Audiobookshelf MCP servers current, evidence-backed, and clearly marked as AI-generated.
Workflow
- Search for public Audiobookshelf MCP servers. Use subagents when the user asks for parallel research or when there are multiple independent targets.
- Prefer direct evidence from project READMEs, releases, registry entries, and package metadata. Treat aggregator pages as secondary evidence.
- Compare each server against this repository's current README,
docs/tools.md,docs/API_TOOL_ANALYSIS.md, and.agents/skills/. - Update the README section between:
<!-- AI-GENERATED-COMPARISON:START --><!-- AI-GENERATED-COMPARISON:END -->
- Set the heading to
## AI Generated Comparison - Last updated YYYY-MM-DDusing the current local date. - Keep the README comparison and candidate gaps descriptive. Do not rank servers or make a recommendation in the README.
- After updating the README, report separate feature gaps or candidate work to the Codex user. Suggestions should be evidence-based and should not imply they are already planned.
- Include a brief operator-focused overview of mutating versus non-mutating coverage. Distinguish read-only inspection/search resources from tools that can change Audiobookshelf state, and call out any safety gates such as read-only mode, explicit enable flags, or destructive confirmations.
- Add a brief
Candidate gaps from this comparisonsubsection inside the README generated block. Include only evidence-backed gaps, mark them as candidates, and link existing GitHub issues when they exist. - Convert the feature gaps into concise candidate GitHub issue titles with one-sentence scopes. Ask the user whether they want issues created for all candidates, a selected subset, or none. Do not create issues unless the user explicitly confirms.
Comparison Criteria
For each credible public server, capture:
What ships with it
1 file 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.

abs-mcp-comparison is a skill published in the GitHub repository jeeftor/abs-mcp (0 stars, last pushed 27d ago), licensed MIT. It adds 51 tokens to every session and 1,054 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
