8a26cfae73 fix(mcp): open MCP OAuth in same browser as gateway (#951)
* fix(mcp): use gateway callback for MCP OAuth so auth opens in same browser

When MCP OAuth is triggered from the web gateway, the auth URL was being
opened via `open::that()` which launches the OS default browser instead
of the browser already running the gateway UI. This changes the MCP OAuth
flow to use the same gateway callback pattern as WASM extensions: in
gateway mode, the auth URL is returned to the frontend via SSE and opened
with `window.open()`, keeping the user in the same browser.

Also adds RFC 8707 `resource` parameter support to the gateway token
exchange path, scoping issued tokens to the correct MCP server.

Closes #299

* fix(mcp): persist DCR client_id in gateway OAuth callback for token refresh

The gateway callback handler stored access and refresh tokens but not
the DCR client_id. When the token expired, refresh failed with "No
client ID found" because get_client_id() could not find it in secrets.

Adds client_id_secret_name to PendingOAuthFlow so the gateway callback
handler persists the client_id alongside the tokens, matching the
behavior of the CLI flow in authorize_mcp_server().

* fix(mcp): return AuthRequired on 401 so activate triggers OAuth flow

activate_mcp() returned ActivationFailed for all errors including 401
auth responses, so the activate handler never triggered the OAuth flow.
Now 401/auth errors return AuthRequired, which the handler detects and
redirects to the OAuth flow — matching the WASM extension pattern.

* fix(mcp): fix gateway OAuth flow, approval cards, and auto-activation

- Add explicit gateway_mode flag on ExtensionManager (set at startup by
  web gateway) so MCP OAuth returns auth URLs to the frontend instead of
  calling open::that() on the server machine.
- Auto-activate extensions after successful OAuth callback so the UI
  transitions from "Activate" to "Active" without a second click.
- Send ApprovalNeeded status (not generic "Awaiting approval") from
  thread_ops.rs for all three NeedApproval paths so the web UI shows
  approval cards for deferred tool calls.
- Remove duplicate ApprovalNeeded send from agent_loop.rs (thread_ops.rs
  is now the canonical sender).
- Skip approval for tool_auth in gateway mode since it only returns a URL.
- Revert fragile active-server detection heuristic from system prompt.

* fix: address PR review findings

- Use Release/Acquire ordering for gateway_mode AtomicBool instead of
  Relaxed to ensure visibility across threads.
- Report activation failure as error in OAuth callback SSE event instead
  of silently falling back to the success message.
- Fix EnvGuard::drop to remove env var when original was unset.
- Replace hardcoded /tmp/ path with std::env::temp_dir() in test helper.

* test(mcp): add E2E trace test for MCP extension lifecycle with mock server

Add a full MCP extension lifecycle E2E test that exercises:
- Turn 1: tool_search → tool_install → text (extension discovery and install)
- Token injection + activate (simulating OAuth completion)
- Turn 2: MCP tool calls (notion-search → notion-fetch → text)

Includes a mock MCP server (tests/support/mock_mcp_server.rs) with OAuth
discovery, DCR, token exchange, and JSON-RPC endpoints. The mock server
validates Bearer auth and serves pre-configured tool responses.

Also adds inject_registry_entry() to ExtensionManager for test use and
exposes extension_manager from TestRig.

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: address PR review findings (round 2)

- Only fall back to manual token entry on AuthNotSupported, propagate
  real errors from auth_mcp_build_url() instead of masking them
- Use mcp:-prefixed provider string in PendingOAuthFlow for consistency
  with CLI MCP auth token storage
- Only persist client_id_secret_name for DCR flows (not pre-configured OAuth)
- Fix gateway_callback_redirect_uri to use /oauth/callback path
- Bypass exchange proxy when flow has RFC 8707 resource parameter
- Remove client_id double-prefix in oauth callback handler
- Remove weak tests that didn't exercise production logic
- Add clarifying comments for exchange_oauth_code delegation

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: keep OAuth success independent of activation, fix wait_for_responses scoping

- OAuth success is now reported accurately even when auto-activation
  fails (tokens are already stored, so auth succeeded)
- E2E test waits for turn1_count + 1 responses to ensure turn-2
  behavior is actually observed

Philosophy

IronClaw is built on a simple principle: your AI assistant should work for you, not against you.

In a world where AI systems are increasingly opaque about data handling and aligned with corporate interests, IronClaw takes a different approach:

  • Your data stays yours - All information is stored locally, encrypted, and never leaves your control
  • Transparency by design - Open source, auditable, no hidden telemetry or data harvesting
  • Self-expanding capabilities - Build new tools on the fly without waiting for vendor updates
  • Defense in depth - Multiple security layers protect against prompt injection and data exfiltration

IronClaw is the AI assistant you can actually trust with your personal and professional life.

Features

Security First

  • WASM Sandbox - Untrusted tools run in isolated WebAssembly containers with capability-based permissions
  • Credential Protection - Secrets are never exposed to tools; injected at the host boundary with leak detection
  • Prompt Injection Defense - Pattern detection, content sanitization, and policy enforcement
  • Endpoint Allowlisting - HTTP requests only to explicitly approved hosts and paths

Always Available

  • Multi-channel - REPL, HTTP webhooks, WASM channels (Telegram, Slack), and web gateway
  • Docker Sandbox - Isolated container execution with per-job tokens and orchestrator/worker pattern
  • Web Gateway - Browser UI with real-time SSE/WebSocket streaming
  • Routines - Cron schedules, event triggers, webhook handlers for background automation
  • Heartbeat System - Proactive background execution for monitoring and maintenance tasks
  • Parallel Jobs - Handle multiple requests concurrently with isolated contexts
  • Self-repair - Automatic detection and recovery of stuck operations

Self-Expanding

  • Dynamic Tool Building - Describe what you need, and IronClaw builds it as a WASM tool
  • MCP Protocol - Connect to Model Context Protocol servers for additional capabilities
  • Plugin Architecture - Drop in new WASM tools and channels without restarting

Persistent Memory

  • Hybrid Search - Full-text + vector search using Reciprocal Rank Fusion
  • Workspace Filesystem - Flexible path-based storage for notes, logs, and context
  • Identity Files - Maintain consistent personality and preferences across sessions

Installation

Prerequisites

  • Rust 1.85+
  • PostgreSQL 15+ with pgvector extension
  • NEAR AI account (authentication handled via setup wizard)

# Clone the repository
git clone https://github.com/nearai/ironclaw.git
cd ironclaw

# Build
cargo build --release

# Run tests
cargo test

For full release (after modifying channel sources), run ./scripts/build-all.sh to rebuild channels first.

Database Setup

# Create database
createdb ironclaw

# Enable pgvector
psql ironclaw -c "CREATE EXTENSION IF NOT EXISTS vector;"

Configuration

Run the setup wizard to configure IronClaw:

ironclaw onboard

The wizard handles database connection, NEAR AI authentication (via browser OAuth), and secrets encryption (using your system keychain). Settings are persisted in the connected database; bootstrap variables (e.g. DATABASE_URL, LLM_BACKEND) are written to ~/.ironclaw/.env so they are available before the database connects.

Alternative LLM Providers

IronClaw defaults to NEAR AI but works with any OpenAI-compatible endpoint. Popular options include OpenRouter (300+ models), Together AI, Fireworks AI, Ollama (local), and self-hosted servers like vLLM or LiteLLM.

Select "OpenAI-compatible" in the wizard, or set environment variables directly:

LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://openrouter.ai/api/v1
LLM_API_KEY=sk-or-...
LLM_MODEL=anthropic/claude-sonnet-4

See docs/LLM_PROVIDERS.md for a full provider guide.

Security

IronClaw implements defense in depth to protect your data and prevent misuse.

WASM Sandbox

All untrusted tools run in isolated WebAssembly containers:

  • Capability-based permissions - Explicit opt-in for HTTP, secrets, tool invocation
  • Endpoint allowlisting - HTTP requests only to approved hosts/paths
  • Credential injection - Secrets injected at host boundary, never exposed to WASM code
  • Leak detection - Scans requests and responses for secret exfiltration attempts
  • Rate limiting - Per-tool request limits to prevent abuse
  • Resource limits - Memory, CPU, and execution time constraints
WASM ──► Allowlist ──► Leak Scan ──► Credential ──► Execute ──► Leak Scan ──► WASM
         Validator     (request)     Injector       Request     (response)

Prompt Injection Defense

External content passes through multiple security layers:

  • Pattern-based detection of injection attempts
  • Content sanitization and escaping
  • Policy rules with severity levels (Block/Warn/Review/Sanitize)
  • Tool output wrapping for safe LLM context injection

Data Protection

  • All data stored locally in your PostgreSQL database
  • Secrets encrypted with AES-256-GCM
  • No telemetry, analytics, or data sharing
  • Full audit log of all tool executions
