What is notion-local-ops-mcp AGENTS.md?

A set of instructions for a local server that lets Notion AI agents work with files, search, shell commands, and delegated coding tasks on your computer.

Use it when developing, configuring, or extending the notion-local-ops-mcp server, including its file tools, search, command execution, and task delegation.

It explains the server's purpose, structure, and available tools so an agent can use it consistently. It also documents how the Python service is arranged and configured.

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	$0.01228	$0.01228
Opus 5.5	$0.00491	$0.00491
Sonnet 5.5	$0.00246	$0.00246

Security

Grade A, and why

notion-local-ops-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 2mo 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.

AGENTS.md — notion-local-ops-mcp

What is this?

A local MCP (Model Context Protocol) server that gives Notion AI agents the ability to operate on your local filesystem and shell. Built with Python 3.11+ and FastMCP, served over SSE on http://127.0.0.1:8766/mcp.

Tools exposed

Tool	Purpose
`server_info`	Inspect runtime config and available MCP tools
`set_default_cwd` / `get_default_cwd`	Manage session default working directory
`list_files`	List directory contents (flat or recursive)
`search`	Canonical unified query tool (glob/regex/text); hides hidden and `.gitignore`d paths by default and supports regex/text against a single file
`read_text`	Canonical single/batch text reader with line pagination and optional line numbers
`write_file`	Create or overwrite a file (`dry_run` supported)
`apply_patch`	Default edit tool for existing files; rejects pure-context hunks, requires unique matches, and supports validation/dry-run
`git_status` / `git_diff` / `git_commit` / `git_log` / `git_show` / `git_blame`	Structured git workflows (when cwd is actually inside a git repo)
`run_command`	Execute a shell command (sync or background)
`run_command_stream`	Start long shell command and poll via task id
`delegate_task`	Submit long-running task to codex/claude-code with optional structured output parsing
`get_task` / `wait_task`	Poll or block on delegated/background task completion
`cancel_task`	Cancel a running delegated task
`purge_tasks`	GC old task logs under `STATE_DIR/tasks`

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.
