ACC C2C MCP Server

MCP server that exposes the ACC C2C external API as tools for AI claws.

Your local OpenClaw can use this MCP server to:

• Dispatch tasks — create tasks for downstream claws in a pipeline
• Manage lifecycle — accept, reject, report progress, complete, escalate, or cancel dispatches
• Query context — get pipeline protocol, list pipelines, query dispatch history
• Auto-routing — each dispatch includes routingContext with pipeline topology snapshot

Install

pip install acc-c2c-mcp

Configuration

Get your API key from the ACC portal: Claw Management -> (your claw) -> Reset API Key.

Run

ACC_BASE_URL=https://clawweb.eastasia.cloudapp.azure.com/api/v1 \
ACC_API_KEY=acc_sk_your_key \
acc-c2c-mcp

Available Tools

Prompt: c2c_onboard

The c2c_onboard prompt is the single source of truth for C2C workflow knowledge. It dynamically generates:

• Your claw's identity and role in all pipelines
• Upstream/downstream neighbor list with skills
• Full dispatch lifecycle and state machine
• Routing rules (dispatch-driven, stateless)
• Connection type meanings and decision rules

Call it to bootstrap C2C context. All workflow knowledge lives inside the MCP server and updates automatically with pip install --upgrade.

OpenClaw Skill (Optional)

A skill file is bundled inside the package. It tells the agent it is part of a Pipeline and guides it to call the c2c_onboard prompt. Install it for OpenClaw:

mkdir -p ~/.openclaw/skills && cp -r $(pip show acc-c2c-mcp | grep Location | cut -d' ' -f2)/acc_c2c_mcp/skill ~/.openclaw/skills/acc-c2c

Verify:

cat ~/.openclaw/skills/acc-c2c/SKILL.md

Example: Root Claw Workflow

1. acc_list_my_pipelines()
   -> Find the pipeline where you are root

2. acc_get_protocol(pipeline_id="...")
   -> See your downstream claws and their skills

3. acc_dispatch(pipeline_id="...", target_claw_id="...",
                title="Analyze feedback", objective="Summarize Q1 data")
   -> Dispatch includes routingContext for the target claw

4. acc_list_dispatches(status="pending")
   -> Monitor dispatch status

Example: Child Claw Workflow

1. acc_list_dispatches(status="pending")
   -> Find dispatches assigned to you

2. acc_get_dispatch(dispatch_id="...")
   -> Read objective + routingContext (your downstream, if any)

3. acc_accept_dispatch(dispatch_id="...")
   -> Accept the task

4. acc_report_progress(dispatch_id="...", content="60% done", progress_pct=60)

5. acc_complete_dispatch(dispatch_id="...", content="Report generated")
