About Tier 1 Protocol
Tier 1 Protocol is a document-search library for agents, returning exact passages with verifiable records. It is aimed at users who need to check source material rather than rely on guessed answers; files are cut and sealed on the user's machine.
Key features
- 01Search authorized document sources
- 02Fetch records by address
- 03Re-verify SHA-256 seals on fetch
- 04Render search results as context
- 05Flag records that fail verification
Use cases
- 01Search records for a specific event or time range
- 02Retrieve cited passages from source documents
- 03Check whether a retrieved record has changed
- 04Use document evidence in an agent response
MCP support
The MCP server exposes source authorization, search, fetch, and context-rendering tools to clients such as Bolt. Fetched records are checked against their SHA-256 seals.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From the project READMETier 1 Protocol — Connector for Bolt
Tier 1 Protocol is a library your AI searches instead of guessing from. Documents are cut into records, each one sealed with SHA-256 at its exact byte address, and served through a single MCP door: your agent asks, the door returns the exact passages — and the proof recomputes on every fetch.
Add it to Bolt (about a minute)
- From the Bolt homepage, click the + by the chat box → Connectors → Manage connectors → Custom MCP server.
- Fill in exactly:
- Name:
Tier 1 Protocol - URL:
https://mcp.tier1protocol.app/mcp - Transport:
HTTP - Authentication:
MCP OAuth
- Name:
- Click Connect and sign in with your Tier 1 account.
- Back in your project, toggle Tier 1 Protocol on.
- Ask your agent: "Using Tier 1, search the starter library: what happened in this account between 23:41 and 00:19?"
The agent should answer from the sealed records and cite record addresses. One record in the starter library — ticket-0007 — fails its verification check on purpose. That's the receipt doing its job: a record that doesn't check out gets flagged, not smoothed over.
The tools
Bolt discovers these from the server at connect time:
| Tool | What it does |
|---|---|
authorize_sources | Lists the sources your agent may search |
search | Finds the records that answer a question |
fetch | Retrieves a record by address and re-verifies its seal |
render_context_results | Renders search results as context your agent can use |
The starter library
Every Tier 1 account begins with the same starter library: the Northpine sample — 282 records across 9 documents, sealed at revision 6bf3c9cb1af2. It's small on purpose. Ask it the 23:41 question and watch the whole loop — search, fetch, verify — run on material you can check by hand.
Your own library
Build your library in your browser at tier-1-protocol-kfn8.bolt.host — your files are cut and sealed on your machine, and the door is what you pay for:
- $19/month for door access, or
- a 3-day free trial, no card, if you want to watch it work first.
The paywall is the door, not the app.
Notes
- Connectors serve Bolt build sessions — that's where the agent calls the door. A published app that needs Tier 1 at runtime calls the same endpoint from its own code, like any external service.
- The door asks you to sign in with your Tier 1 account (MCP OAuth). Your library is fenced to your account.
- This repository is the setup sheet only. There is no product code in it.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
