01 / Connect

Use it where you work.

Connect this remote MCP server to Codex, ChatGPT, or Claude. Use the same endpoint in each client; follow its setup path below.

Codex
Add the remote server

Run this in a terminal where the Codex CLI is installed. The CLI and IDE extension share this configuration.

Open the existing listing

Use the ChainSourced listing to connect the MCP server in ChatGPT. Check the listing's current availability and follow any workspace controls.

Codex CLI and Claude Code commands are documented by their vendors. Claude web connectors and ChatGPT custom MCP setup may vary by plan or workspace administration; the ChainSourced ChatGPT listing is provided above.
02 / Coverage

Know what a match means.

These counts describe the published, reviewed index. They do not describe every entity, address, network, or relationship that exists.

Search results are evidence-linked relationships between public entities, blockchain addresses, and public accounts such as domains or repository namespaces.

An empty result means “no reviewed mapping in this index.” It does not prove that an address has no relationship elsewhere.

Use get_coverage for the current snapshot. Each result includes its recorded relationship and source link for independent inspection.

Source-backedExact artifacts and pinned source revisions are retained with applicable notices.
Independently reviewedRights and each proposed public relationship pass separate review before release.
Read-only lookupsTool calls query published records; they do not collect data or publish changes.

Additional tools may return approved cached contract metadata and chain observations with source, block, age, and coverage details. A published artifact does not establish ownership, deployed bytecode, or contract safety.

03 / Sources

Evidence stays visible.

Each relationship links to its primary evidence. Archived notices below preserve license terms for source materials; their presence does not mean every source candidate is published.

What the index can say

A deployment listing, website, or repository may establish a specific public relationship. It does not establish personal wallet ownership, current control, endorsement, bytecode verification, or contract safety.

What a missing match can say

The registry has limited coverage. Rights changes, source withdrawals, or review can change which records are published. Check the primary source and date before relying on a result.

04 / Try it

Ask a specific question.

Choose a client after connecting and ask for a lookup with its exact chain or public account identifier.

Address lookup

“What reviewed relationship is recorded for this Ethereum address? Show the source.”

Entity lookup

“Find Safe in the reviewed index and list its recorded addresses and public accounts with source links.”

Available tools include lookup_address, lookup_account, search_entities, get_entity, and get_coverage, get_observation_coverage, get_contract_metadata, and get_onchain_snapshot, and list_address_transactions. Use the live server to inspect its current tool list.
