Trustbase Lab for AI AgentsAgent-Ready v1.8
The recovered carbon black (rCB) industry database is exposed as a machine-readable interface. Every record carries a stable entity ID, fields are bilingual, and the full schema is public. Our MCP server is live on the official MCP Registry under com.trustbaselab/rcb-data. Data is free to use; please cite the source.
1. Quick Start — three lines
No auth, no signup. POST JSON-RPC 2.0 messages to the public MCP endpoint. Default response language is English.
curl -X POST https://trustbaselab.com/mcp \ -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_database_overview","arguments":{"language":"en"}}}'
2. Connection modes
A · Public HTTPS endpoint recommended
Any MCP client that supports Streamable HTTP can connect directly to https://trustbaselab.com/mcp. No local server required — send JSON-RPC and call all 27 tools.
B · MCP Official Registry new
Listed on the official registry as com.trustbaselab/rcb-data (status: active). Clients with Registry discovery can search by name and install in one click. Domain ownership verified via HTTP /.well-known.
C · Local stdio
For Claude Desktop, Cursor, Cline and other local agents. Zero third-party dependencies (Python standard library only). The script auto-fetches fresh data from this site's public endpoint on each call.
D · Direct JSON endpoints
Any agent, crawler or script can GET the JSON endpoints below — no MCP support needed.

6. Entity IDs & confidence
Every company record carries a stable entity ID. New records only append — existing IDs are never changed — so long-term citations stay valid.
| Group | ID prefix | Example |
|---|---|---|
| China domestic companies / projects | rcb-cn-### | rcb-cn-001 |
| International companies | rcb-gl-### | rcb-gl-003 |
| Equipment vendors | rcb-eq-### | rcb-eq-001 |
| Policies & regulations | rcb-pol-### | rcb-pol-001 |
| Technical standards | rcb-tech-### | rcb-tech-001 |
| Carbon black grades (native / conductive / rCB) | rcb-grade-* | rcb-grade-n550 |
| Trade flows (UN Comtrade HS 280300) | cb-trade-{iso}-{partner}-{YYYY}-{x|m} | cb-trade-chn-764-2024-x |
| Knowledge cards | CB-YYYYMMDD-### | CB-20260917-001 |
Confidence levels: A = verified against government documents / official announcements; B = company self-disclosure / authoritative media; C = unverified / disputed. When citing, keep the confidence label attached — do not treat B/C-grade data as conclusions.
Verified Supplier: public.verified=true ⟺ gated.confidence=A. Currently 49 / 101 companies verified; 209 / 2,098 records are A-grade across the full dataset.
Verified Supplier: public.verified=true ⟺ gated.confidence=A. Currently 49 / 101 companies verified; 209 / 2,098 records are A-grade across the full dataset.
7. Agent Skills (judgment layer)
Beyond raw data, we publish 4 reusable Skills — rules only, no data (per the Agent Skills open standard). Use them for higher-level judgement.
| Skill | Purpose | Install |
|---|---|---|
| rcb-substitution-assessment | Four-factor rCB substitution assessment (quality discount + grade limit + certification + cost) | /skills/rcb-substitution-assessment/SKILL.md |
| rcb-price-reference | When and how to cite rCB price reference data without overstating | /skills/rcb-price-reference/SKILL.md |
| rcb-export-compliance | Match rCB shipments against CBAM / EUDR / national rules | /skills/rcb-export-compliance/SKILL.md |
| rcb-grade-identification | Identify ASTM D1765 native grades + ASTM D8632 rCB grades | /skills/rcb-grade-identification/SKILL.md |
Index & full text at /skills/index.json. Principle: MCP is the data layer, Skills are the judgement layer — Skills never carry data tables.
8. Rate limits, SLA & version
| Aspect | Value |
|---|---|
| Endpoint | https://trustbaselab.com/mcp (HTTPS, public, no auth) |
| Transport | Streamable HTTP (primary) / stdio (local) |
| CORS | Access-Control-Allow-Origin: * — any agent can connect |
| Rate limit | None today; soft-throttling if abuse is detected |
| Data version | v0.10 / schema 1.8 |
| MCP server version | 1.8.0 |
| Update frequency | Master data: as source data updates · Index/llms.txt/mcp.json: rebuilt on every deploy |
| Uptime SLA | Best-effort. Cache-friendly: static JSON endpoints tolerate >24h of MCP downtime. |
| Breaking changes | Schema version bumps with a public changelog; agent-facing endpoints stay backwards-compatible within a major version. |
