What is Code-Index-MCP AGENTS.md?

Repository instructions for Code-Index-MCP, a code-search service that uses text and meaning-based indexes to find code. They describe its current architecture, supported interfaces, repository rules, and limits of indexed results.

Use it when working on Code-Index-MCP, configuring its agent interface, checking search readiness, or investigating index and repository behavior.

They help agents know when search results are trustworthy and when to use ordinary local search instead. They also explain that the project is still in an early stage and may change.

Token cost

What it costs to keep this loaded

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	$0.05001	$0.05001
Opus 5.5	$0.02000	$0.02000
Sonnet 5.5	$0.01000	$0.01000
Haiku 4.5	$0.00500	$0.00500

Security

Grade A, and why

Code-Index-MCP AGENTS.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 24d 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.

Current State

System Complexity: 5/5 (High — SQLite FTS5 + Qdrant vector index, 48 language plugins, rerankers, query-intent routing) MCP Status: Use MCP indexed search when repository readiness is ready; STDIO is the primary surface Last Updated: 2026-04-23 Support matrix: Customer-facing language/runtime support claims live in docs/SUPPORT_MATRIX.md. Dependency truth: Use uv sync --locked; pyproject.toml and uv.lock are canonical.

Current verification boundary: docs/status/V13_EXECUTION.md tracks active hardening. Language registry inventory and earlier implementation summaries are not installed-runtime, platform, or fleet acceptance. Keep the existing support tiers in docs/SUPPORT_MATRIX.md and record untested combinations.

Beta status: Multi-repo support and the STDIO interface are in beta. STDIO is the primary surface for LLM tool calls; FastAPI is a secondary admin surface for diagnostics and manual operations. Expect API surface changes before stable release.

Public alpha repository model: v3 supports many unrelated repositories on one machine, with one registered worktree per git common directory. Only the tracked/default branch is indexed automatically. Indexed results are authoritative only when readiness is ready; unavailable indexes return index_unavailable with safe_fallback: "native_search".

What's Actually Implemented

✅ STDIO transport (search_code, symbol_lookup, summarize_sample, reindex MCP tools)
✅ FastAPI admin surface with endpoints: /symbol, /search, /status, /plugins, /reindex
✅ Dispatcher with caching and auto-initialization
✅ Python plugin fully functional with Tree-sitter + Jedi
✅ JavaScript/TypeScript plugin fully functional with Tree-sitter
✅ C plugin fully functional with Tree-sitter
✅ SQLite persistence layer with FTS5 search
✅ File watcher auto-starts in initialize_services() after dispatcher is ready; stopped in main() finally block on exit (EnhancedDispatcher mode only)
✅ Error handling and logging framework
✅ Comprehensive testing framework (pytest with fixtures)
✅ CI/CD pipeline with GitHub Actions
✅ Docker support and build system

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.
