o3r-local

o3r-local is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from AmadeusITGroup/otter. Its token cost is not measured, scanned A, original, BSD-3-Clause.

An MCP server package launched from the o3r project. MCP is a standard way for an agent to connect to external tools, but this description does not explain which tools are available.

In plain words
What is it for?
It provides a locally launched MCP server, but its concrete jobs are not described.
Why use it?
The available information is not enough to identify a specific problem it solves.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Written for no agent in particular: it speaks MCP, so any client can run it.

One of 5 entries in mcp.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

Good fit It provides a locally launched MCP server, but its concrete jobs are not described.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

o3r-local 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 yesterday.

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 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.
