Òtítọ́ MCP server – quality and maintenance score on Glama

Otito is a local-first, deterministic, model-agnostic trust layer for AI-assisted development. It builds task-aware repository context before an agent edits, scores how much a change actually touches, and gates merge readiness against the exact staged tree, with no server, no account, and no code leaving the machine.

It does not replace Claude Code, Codex, Cursor, Gemini, or any native agent harness. It runs beside them and keeps working as the models change underneath.

A passing local gate is never an automatic merge approval: hosted CI, GitHub review, CODEOWNERS, and the human release decision remain separate authorities.

Install

npm install -g @bashbop/otito
otito doctor

Or without installing: npx -y @bashbop/otito doctor.

What it does

Rank what a change actually touches, from the request alone, with no model, no embeddings, and no network:

$ otito impact . "add refund handling to checkout" --top 3

  concepts: money flow

   1.  src/payment/checkout.service.ts    score 155
       |- role: required
       |- path matches: checkout
       |- symbol matches: checkout, refund
       |- concept match: money flow (×1.4 + 6.0)
       |- risk: money flow

   2.  src/payment/stripe.webhook.ts    score 6
       |- role: advisory
       |- concept match: money flow (×1.4 + 6.0)

Gate the exact staged tree, and say precisely why:

$ otito gate . --staged --base origin/main --request "add refund handling to checkout" --min-convergence 80

  [OK]    Changed files          1 changed file found.
  [OK]    Staged snapshot        Changed-file scope and convergence evidence are captured from the exact staged Git tree.
     |- Tree: 7d0b513dd256877d6bd309a6406468a9b1eaeedc
     |- Base: b776f04fcfbd02c8ce8d63e1a0c2450be58de039
  [OK]    Secret safety          No secret file paths and no credential values found in the changed content.
  [WARN]  Risk review            Risk-sensitive files changed; maintainer review should be explicit.
     |- src/payment/checkout.service.ts
  [OK]    Convergence            Task and diff satisfy the convergence requirement.
     |- Score: 100/100 (aligned)
     |- Receipt handle: rcpt_a8d31efae06e
     |- Subject tree: 7d0b513dd256877d6bd309a6406468a9b1eaeedc

  VERDICT  WARN

The convergence score is the part a model cannot grade for itself: it compares the stated intent against the files the diff actually changed, and produces a receipt bound to the exact base, parent, and staged-tree identity.

The core

Three commands are the product. They call no model, open no socket, and read nothing outside the repository.

Nothing hosted is required, and nothing hosted can change a verdict. Local Core, Optional Hosted lists exactly what the optional pieces send, and where.

Supporting commands

Every command takes --json, and otito help lists the full set with flags.

MCP

Otito ships a stdio MCP server exposing 14 tools: repo_inspect, repo_map, repo_index, repo_search, context_pack, change_impact, agent_experience, model_route, convergence_score, review_context, review_gate, review_verdict, workspace_report, and repo_harness.

{
  "mcpServers": {
    "otito": {
      "command": "npx",
      "args": ["-y", "@bashbop/otito", "mcp"]
    }
  }
}

Published in the MCP Registry as io.github.BASHBOP/otito. Repo-map lookups use an external per-user cache and never write into the inspected repository. Host-specific setup for Claude Code, Claude Desktop, Codex, Cursor, VS Code, Gemini CLI, and Kimi Code is in MCP and Agent Workflows.

Contributing

git clone https://github.com/BASHBOP/otito.git
cd otito && npm ci && npm run ci

npm run ci is the full gate: format, lint, typecheck, version check, tests, coverage floors (70% lines / 60% branches / 75% functions), three evaluation corpora, dependency audit, and a packaged-tarball smoke test. Run it before requesting review.

Start with CONTRIBUTING.md and the Code of Conduct. All changes need maintainer review; main requires passing gates and resolved conversations. Otito follows Semantic Versioning, so say whether a PR is no-impact, patch, minor, or major.

Part of the toolchain

otito is one of four tools that form a deterministic trust layer for AI-assisted development. Each uses static analysis to answer a question people keep handing to an LLM.

• otito (this tool), for context: what does this change actually touch?
• tieline, for contracts: did the front end and back end quietly stop agreeing?
• bouncer, for compliance: could you defend this to Ofcom?
• aiglare, for governance: where can the model do something you can't undo?
