Common questions

Is writ safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: WRIT_API_KEY, WRIT_SPONSOR_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.2.2) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

writ-mcp

The Writ gate as an MCP server. Give any MCP-compatible agent point-of-action control: the agent calls Writ before a consequential write, gets back ALLOW, DENY, or STEP_UP, and every outcome creates an audit receipt.

Install

pip install writ-mcp

Requires Python 3.9+. Installs the writ-mcp command (stdio transport).

Configure

export WRIT_API_KEY="writ_..."        # required; get one free: POST /v1/keys with an email

export WRIT_SPONSOR_TOKEN="..." # only for sponsor tools (grant, revoke, reinstate)

export WRIT_BASE_URL="..." # default: https://api.withwrit.com

Add to your agent

Claude Code:

claude mcp add writ --env WRIT_API_KEY="$WRIT_API_KEY" -- writ-mcp

Claude Desktop (claude_desktop_config.json):

"mcpServers": { "writ": { "command": "writ-mcp", "env": { "WRIT_API_KEY": "writ_..." } } } }

Any MCP client (generic stdio config):

"command": "writ-mcp", "env": { "WRIT_API_KEY": "writ_...", "WRIT_SPONSOR_TOKEN": "writ_sp_..." } }

Hermes (NousResearch/hermes-agent) catalog entry — once published, this package is installable from the optional-mcps catalog:

hermes mcp install writ

The check-before-write loop

The tool descriptions teach the agent this flow, but the short version:

writ_check(sponsor_id, agent_id, verb, target, purpose) — before the write.
ALLOW → you get a 90-second authToken bound to that exact write.
writ_verify_token(auth_token, verb, target, purpose) — immediately before executing, to prove the authorization still matches what you're doing.
DENY → do not proceed. STEP_UP → a human sponsor approves (via writ_grant or the dashboard), then check again.

Tools

Tool	Who	What
`writ_check`	agent	Decision + 90s purpose-bound token
`writ_verify_token`	agent	Point-of-action token verification
`writ_grant`	sponsor	Approve a STEP_UP (one-time grant)
`writ_revoke` / `writ_reinstate`	sponsor	Kill switch on/off for a principal
`writ_receipts`	agent	Audit trail of decisions
`writ_policy`	agent	Tenant verb policy
`writ_sandbox`	anyone	Free 90-second demo grant, no key needed
`writ_github_installations`	admin	List connected GitHub App installations
`writ_github_set_threshold`	admin	Set the check-run fail threshold per install
`writ_github_toggle_pr_comments`	admin	Enable/disable the PR-comment bot
`writ_manifests`	agent	List repos with risk profiles or fetch one manifest
`writ_explain_receipt`	agent	Explain a receipt in plain language
`writ_tenant_notify`	admin	Get or update step-up notification settings
`writ_principals`	admin	List the tenant's principals
`writ_verbs`	admin	List the tenant's verb vocabulary
`writ_keys`	admin	List API key metadata

Try it with no key: writ_sandbox → writ_check with verb="demo_write".
