Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Set autopilot scopes and a daily SOL spend cap, then propose, execute, and undo agent actions.
These three are never merged into one score: opinions, measurements and popularity are different things.

@three-ws/autopilot-mcp
An AI agent's own autonomous-execution control plane — set autopilot scopes, a daily SOL spend cap, and auto-execute, then run the propose → execute → undo loop, all from any MCP client.
A Model Context Protocol server that gives an AI agent its own execution control plane over stdio. The agent configures the boundaries it is allowed to act within — capability scopes, a daily SOL spend ceiling, auto-execute and confirmation policy — then drives the full propose → review → execute → undo loop. No human in the loop, but every boundary is enforced server-side: an out-of-scope or over-budget action is denied, never executed.
This is the keystone of the autonomous-agent story. Autopilot config and execution used to live only behind the three.ws UI/API; this server exposes them so an agent can manage its own guardrails and act within them.
⚠️ This server is authenticated and write-heavy.
execute_proposalcan move real SOL on Solana mainnet and is irreversible. It sends native SOL only — the agent never sells or sends $THREE (it only buys, holds, or burns it). Scopes, the daily SOL spend cap, and confirmation are all enforced on the three.ws backend — this server cannot bypass them.
npm install @three-ws/autopilot-mcp
Or run with npx (no install):
npx @three-ws/autopilot-mcp
Claude Code, one line (supply your three.ws credential):
THREE_WS_API_KEY=sk_live_… claude mcp add autopilot -- npx -y @three-ws/autopilot-mcp
Claude Desktop / Cursor (claude_desktop_config.json or mcp.json):
{
"mcpServers": { "autopilot": { "command": "npx", "args": ["-y", "@three-ws/autopilot-mcp"], "env": { "THREE_WS_API_KEY": "sk_live_…" } } } }
Inspect the surface with the MCP Inspector:

Every autopilot endpoint is owner-only, so this server is authenticated. Set `THREE_WS_API_KEY` to the agent owner's three.ws credential — either a three.ws API key (sk_live_… / sk_test_…) or an OAuth access token. It is sent as Authorization: Bearer … on every request and identifies the owning user; the agent can only manage agents that user owns. The credential can authorize real SOL transfers via execute_proposal — store it like a password. THREE_WS_TOKEN and THREE_WS_BEARER are accepted as aliases.
| Tool | Type | What it does |
|---|---|---|
get_autopilot_config | read-only | Read the agent's guardrails: enabled, scopes, auto-execute, daily SOL cap, confirmation policy — plus trust. |
set_autopilot_config | write · idempotent | Update those guardrails with a partial patch (grant scopes, set the daily SOL ceiling, arm/disarm). No action taken. |
generate_proposals | write | Run the agent's mind: turn high-salience memories + reflections into real, provenance-cited candidate actions. |
list_proposals | read-only | The proposal queue — ids, kinds, rationales, params, status, cited sources. Filter by status. |
dryrun_proposal | read-only | Preview what executing a proposal *would* do (scope / cap / balance checks), without taking any action. |
adjust_proposal | write · idempotent | Edit a pending proposal's params before executing (tune a threshold, amount, cadence). Validated server-side. |
execute_proposal | write · destructive | Take the real action. ⚠️ A wallet_transfer or trade moves real funds on mainnet, irreversible. needs confirm:true. Never sends or sells $THREE. |
dismiss_proposal | write | Drop a pending proposal; records a feedback memory so the agent stops proposing it. |
undo_action | write | Reverse a reversible execution (delete the alert rule / briefing); records a feedback memory. SOL transfers can't be undone. |
list_autopilot_activity | read-only | The append-only signed receipts log — every autonomous action, its outcome, provenance, and signature. |
compute_trust | read-only | The agent's earned trust level (sandbox → trusted → autonomous), computed from real action history. |
The five read tools reflect live state (proposals, receipts, trust move between calls), so none are idempotent. set_autopilot_config and adjust_proposal are idempotent writes (re-applying the same values is a no-op). generate_proposals, execute_proposal, dismiss_proposal, and undo_action each take a real action.
Every tool takes `agentId` (the UUID of an agent you own) except list_autopilot_activity, where it is optional (omit to aggregate across all your agents).

Spending real SOL requires the owner to have granted scopes.wallet_transfer, set a positive dailySpendSol, and (unless pre-authorized) execute_proposal must be re-issued with confirm:true. All three are checked server-side. A trade proposal (a buy with SOL or a sell of a non-$THREE token) needs scopes.trade and runs the same wallet guards as the wallet hub. Buys count against dailySpendSol. The agent spends SOL only, it never sells or sends $THREE; a $THREE sell is refused at proposal validation.
THREE_WS_API_KEY) for the agent owner.https://three.ws (or your own THREE_WS_BASE).| Variable | Required | Default | Notes |
|---|---|---|---|
THREE_WS_API_KEY | yes | — | three.ws API key (sk_live_…) or OAuth access token. Secret. Can move real SOL. |
THREE_WS_BASE | no | https://three.ws | Override only when self-hosting or targeting a preview. |
THREE_WS_TIMEOUT_MS | no | 60000 | Per-request timeout (generation runs a server-side LLM pass). |
