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 | $0.01391 | $0.01391 |
| Opus 5.5 | $0.00556 | $0.00556 |
| Sonnet 5.5 | $0.00278 | $0.00278 |
| Haiku 4.5 | $0.00139 | $0.00139 |
Grade A, and why
cclsp CLAUDE.md 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.

Project Overview
cclsp is an MCP (Model Context Protocol) server that bridges Language Server Protocol (LSP) functionality to MCP tools. It allows MCP clients to access LSP features like "go to definition" and "find references" through a standardized interface.

Architecture
Core Components
MCP Server Layer (index.ts)
- Entry point that implements MCP protocol
- Exposes
find_definition,find_references, andrename_symboltools - Handles MCP client requests and delegates to LSP layer
- Includes subcommand handling for
cclsp setup
LSP Client Layer (src/lsp-client.ts)
- Manages multiple LSP server processes concurrently
- Handles LSP protocol communication (JSON-RPC over stdio)
- Maps file extensions to appropriate language servers
- Maintains process lifecycle and request/response correlation
- Auto-detects and applies server-specific adapters
Server Adapter System (src/lsp/adapters/)
- Built-in adapters for LSP servers with non-standard behavior
- Vue Language Server adapter handles custom
tsserver/requestprotocol - Pyright adapter provides extended timeouts for large projects
- Automatically detected based on server command (no configuration needed)
- Internal use only - not user-extensible
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.

cclsp CLAUDE.md is an instructions file published in the GitHub repository ktnyt/cclsp (676 stars, last pushed 8mo ago), licensed MIT. It adds 1,391 tokens to every session, about $0.0056 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.
