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 | $0.00011 | $0.00309 |
| Opus 5 | $0.00005 | $0.00154 |
| Sonnet 5 | $0.00002 | $0.00062 |
| Haiku 4.5 | $0.00001 | $0.00031 |
Grade A, and why
add-tool 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 11d 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
Task
Add a new MCP tool to yandex-wiki-search-mcp.
Always follow @CLAUDE.md.
Instructions
- Keep the implementation aligned with the current Wiki architecture:
- protocol in
mcp_wiki/wiki/proto/pages.py - models in
mcp_wiki/wiki/proto/types/pages.py - HTTP implementation in
mcp_wiki/wiki/custom/client.py - MCP registration in
mcp_wiki/mcp/tools/page_read.pyormcp_wiki/mcp/tools/page_write.py
- protocol in
- If the tool is read-only, register it only in
page_read.py. - If the tool mutates Wiki state, register it only in
page_write.pyand make sure it is hidden in read-only mode. - Add or update tests:
- HTTP-level tests in
tests/wiki/custom/when client behavior changes - MCP-level tests in
tests/mcp/tools/ - registration checks in
tests/mcp/server/test_server_creation.pywhen a new tool is added
- HTTP-level tests in
- Update
@README.md,@README_ru.md,@manifest.json, and@CHANGELOG.md.

$ARGUMENTS
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.
- 11d ago First seen · 30 lines · 11 tokens per session scan A 42d3f2926f47
add-tool is a command published in the GitHub repository dlbolshov/yandex-wiki-search-mcp (6 stars, last pushed 16d ago), licensed Apache-2.0. It adds 11 tokens to every session and 309 once invoked, about $0.0001 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.
