## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json

Recommended repository topics and listing keywords:

Indexing checklist:

- Submit `https://mcp.blocksize.info/sitemap.xml` in Google Search Console and Bing Webmaster Tools.
- Request indexing for the homepage, data package catalog, and every canonical intent page above.
- Use the MCP manifest, `server.json`, `llms.txt`, OpenAPI JSON, and `data-packages.json` as the canonical machine-readable citations in marketplaces, docs, and repo descriptions.
- Use `category-hubs.json` for dated coverage states, rights boundaries, methodology, and citation instructions. Cataloged, candidate, and production-promoted coverage are intentionally separate states.

RWA claims boundary:

- Blocksize already provides broad production coverage across its live market-data packages.
- Separately, the reconciled 2026-07-30 RWA research snapshot contains 1,169
  RWA.xyz source-asset rows and 3,438 token-listing rows (3,435 unique contract
  identities). Its lossless cross-venue matrix contains 2,139 canonical assets
  and 5,161 venue instruments; these are catalog and identity grains, not
  production-feed counts.
- Candidate expansion lanes are not additional production feeds until their promotion gates pass.
- Zero newly sourced third-party or onchain additions have completed the full RWA expansion-workflow promotion process. This figure does not describe or reduce existing Blocksize production coverage.
- Hash-linked provenance receipts are not described as cryptographically signed unless a response includes a signature envelope with an algorithm, key identifier, digest, and signature.

## Product Shape

### 1. Public remote MCP discovery server

The remote MCP server is meant for directory listings and fast evaluation in ChatGPT Developer Mode, Cursor, Claude MCP clients, Smithery, Glama, and other Streamable HTTP clients.

It exposes only read-only discovery tools:

- `search_pairs`
- `list_instruments`
- `get_pricing_info`
- `get_product_catalog`
- `recommend_account_plan`
- `get_workflow_endpoint`
- `get_market_data_endpoint`
- `search`
- `fetch`

This public surface does not execute paid live market data calls directly.

### 2. Paid HTTP market data API

The paid HTTP API is the production data path for live access:

- `GET /v1/vwap/{pair}`
- `GET /v1/bidask/{pair}`
- `GET /v1/fx/{pair}`
- `GET /v1/metal/{ticker}`
- `GET /v1/batch`

Free discovery endpoints:

- `GET /v1/coverage`
- `GET /v1/search`
- `GET /v1/instruments/{service}`
- `GET /v1/samples/market-data?service=vwap&symbol=BTCUSD` for a clearly
  synthetic value preview and attributed paid handoff
- `GET /health`

`/v1/search` is paginated with `limit` and `offset`. Its `total_matches`
field is the full match count for the searched catalogs; the default 50 is
only the response page size and is unrelated to starter credits.

Payment modes:

- signed x402 v2 payment per request via `PAYMENT-SIGNATURE`
- starter credit drawdown through an authenticated Claude, Cursor,
  or OpenAI connector principal

New eligible authenticated users receive 15,000 free live data credits every
calendar month (UTC), positioned as `Start with 15,000 free live-data credits
every month`. The allowance is an evaluation and prototyping licence with
required attribution; production commercial use requires a subscription. The
number is configured once in `FREE_TIER_MONTHLY_CREDITS` (`src/config.py`) and
every surface renders it from there. Raw caller-selected HTTP identity headers
are disabled in production and cannot claim or spend credits. When the monthly
allowance is exhausted, agents can use direct x402 payment, start a subscription
trial at `/go/free-trial` (plans from EUR 49/month, see `/go/pricing`), or
contact Blocksize sales about an Enterprise authenticated account plan.

### 3. Anthropic-safe MCP beta

The Anthropic-safe MCP surface is mounted at `/anthropic/mcp/` and exposes
read-only tools only:

- `search_pairs`
- `list_instruments`
- `get_credit_balance`
- `get_vwap`
- `get_bid_ask`
- `get_fx_rate`
- `get_metal_price`

Live market data tools use server-side free-tier credits keyed to authenticated
user identity. The allowance is 15,000 credits per verified identity per
calendar month (UTC), set by `FREE_TIER_MONTHLY_CREDITS` and shared by the
Claude, Cursor, and OpenAI connectors. The legacy `ANTHROPIC_DAILY_CREDITS`,
`CURSOR_DAILY_CREDITS`, and `OPENAI_DAILY_CREDITS` variables are ignored;
per-user entitlement overrides for subscribers still apply.

For local beta testing, set `ANTHROPIC_ENABLE_BETA_TOKENS=true` and
`ANTHROPIC_BETA_TOKENS` to a JSON object mapping random bearer tokens to user
ids. For public Claude custom connectors, set
`ANTHROPIC_AUTH_PROVIDER=clerk`, keep `ANTHROPIC_ENABLE_BETA_TOKENS=false`, and
configure the Clerk env vars in
[.env.example](https://github.com/jf-cmyk/agentic-payments/blob/HEAD/.env.example).
The Claude OAuth metadata endpoints are served at
`/.well-known/oauth-protected-resource/anthropic/mcp/` and
`/.well-known/oauth-authorization-server/anthropic/mcp`.

### 4. Advanced local MCP

For builders who want the full tool surface inside a local MCP client, this repo also contains the advanced local MCP server in [src/mcp_server.py](https://github.com/jf-cmyk/agentic-payments/blob/HEAD/src/mcp_server.py).

That mode is intended for direct builder integrations and requires local credentials.

## Coverage

Use `GET /v1/coverage` for current source-backed counts and qualification
boundaries. The response separates enabled live discovery namespaces,
decision-grade canonical RWA identities, and research/manual-verification
coverage. Namespace and venue-row counts overlap and must not be summed as a
unique-instrument total.

## Local Development

```bash
uv venv
source .venv/bin/activate
uv pip install -e ".[dev]"
```

Run the HTTP server:

```bash
uvicorn src.resource_server:app --port 8402
```

Run the advanced local MCP server:

```bash
python -m src.mcp_server
```

## Tests

```bash
.venv/bin/python -m pytest tests/ -q
```
