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 | $0.00033 | $0.00968 |
| Opus 5 | $0.00016 | $0.00484 |
| Sonnet 5 | $0.00007 | $0.00194 |
| Haiku 4.5 | $0.00003 | $0.00097 |
Grade A, and why
localnest-mcp 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LocalNest MCP
Local-first MCP server: code retrieval + persistent agent memory. 72 tools, pure SQLite, zero cloud.
Philosophy: evidence-first, capture-always, minimal-ceremony (just {title, content} to store).
Quick Start
localnest_agent_prime({ task: "your task" })-- one call: memories + entities + files + changes + actionslocalnest_find({ query: "..." })-- fused search across memory, code, and KGlocalnest_memory_store({ title: "...", content: "..." })-- save a decision (everything else auto-inferred)
Key Workflows
Cold start: agent_prime replaces 4+ separate calls. Always start here.
Search: find for cross-domain. search_files({ query, project_path }) for paths. search_code({ query, project_path, context_lines: 5 }) for exact symbols. search_hybrid({ query, project_path, max_results: 20 }) for concepts.
Bulk writes: Use _batch variants for 3+ items: memory_store_batch({ memories: [...], response_format: "minimal" }) (100/call), kg_add_triples_batch({ triples: [...] }) (500/call), kg_add_entities_batch({ entities: [...] }) (500/call).
Token savings: Pass terse: "minimal" to any write tool for {id, ok} instead of full payload.
Teach: localnest_teach({ instruction: "always use snake_case in this repo" }) -- persists across sessions.
Recall: memory_recall({ query: "...", nest: "project-name" }). Results include related_facts from KG.
What changed: whats_new({ since: "last_session" }) -- cross-session delta.
Code intel: find_definition({ symbol: "MyClass" }), find_callers({ symbol: "handleAuth" }), find_implementations({ symbol: "Parser" }), rename_preview({ symbol: "oldName", new_name: "newName" }).
KG facts: kg_add_triple({ subject_name, predicate, object_name }). Query: kg_query({ entity_name }). Timeline: kg_timeline({ entity_name }). Point-in-time: kg_as_of({ entity_name, as_of_date }).
Proactive hints: read_file auto-surfaces _memory_hints for linked high-importance memories. After edits: file_changed({ file_path: "..." }) returns memories that may need updating.
What ships with it
5 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.

localnest-mcp is a skill published in the GitHub repository wmt-mobile/localnest (6 stars, last pushed 2mo ago), licensed MIT. It adds 33 tokens to every session and 968 once invoked, about $0.0002 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.
