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 | $0.00031 | $0.01245 |
| Opus 5.5 | $0.00012 | $0.00498 |
| Sonnet 5.5 | $0.00006 | $0.00249 |
| Haiku 4.5 | $0.00003 | $0.00125 |
Grade A, and why
mcp-capability-inventory 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.

MCP capability inventory
Use this skill when
Use this skill when:
- adding, removing, renaming, or changing an MCP tool or resource
- editing README tool/resource counts
- changing
writeEnabled/controlEnabledbehavior - changing route, AUX, Fat Channel, patch-sheet, line-check, or diagnostic tools
- reconciling implementation with docs/issues
Goal
Make the registered MCP surface the single source of truth. Documentation may summarize capability, but it must not manually invent counts or imply more support than the registered tools/resources provide.
Source files
Primary implementation files:
packages/presonus-mcp-server/src/tools.tspackages/presonus-mcp-server/src/resources.ts
Supporting contract files:
packages/presonus-domain/src/**packages/presonus-adapter/src/**README.mddocs/**- relevant GitHub issues and ADRs

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.

mcp-capability-inventory is a skill published in the GitHub repository zarfld/presonus-studiolive-mcp (1 stars, last pushed 4d ago), licensed MIT. It adds 31 tokens to every session and 1,245 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 2026-08-31.
