Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01092 | $0.01092 |
| Opus 5 | $0.00546 | $0.00546 |
| Sonnet 5 | $0.00218 | $0.00218 |
| Haiku 4.5 | $0.00109 | $0.00109 |
Grade A, and why
dflow-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
This is an MCP (Model Context Protocol) server that provides access to the Prediction Market Metadata API. The server wraps the REST API defined in llms_dflow.json and exposes it as MCP tools for use with Claude Desktop, Cursor, and other MCP clients.
Base API URL: https://prediction-markets-api.dflow.net
Commands
Development
# Start server in development mode with hot reload
bun run dev
# Start server in production mode
bun start
# Build the project
bun run build
# Run tests
bun run test
Running the server directly
bun run src/index.ts
Architecture
Single-File MCP Server
The entire server implementation is contained in src/index.ts. This is intentional for simplicity - the server is a thin wrapper around the external API.
Key components:
-
DFlowAPIClient (lines 23-85): HTTP client that handles all API communication
- Implements request timeout handling (30s default)
- Constructs URLs with query parameters
- Handles GET and POST requests
- Returns parsed JSON responses
-
TOOLS array (lines 103-696): Complete tool definitions
- Each tool maps to one API endpoint
- Tool definitions include JSON schemas for parameter validation
- Organized by endpoint category (events, markets, trades, forecasts, candlesticks, live data, series, utilities)
-
Request handlers (lines 698-849):
ListToolsRequestSchema: Returns all available toolsCallToolRequestSchema: Routes tool calls to appropriate API endpoints using a large switch statement- Error handling returns descriptive messages
API Endpoint Categories
The server exposes 25 tools across 8 categories:
- Events: Get individual events, paginated event lists, search events
- Markets: Get markets by ticker or mint address, batch queries
- Trades: Query trade history with filtering and pagination
- Forecasts: Historical forecast percentile data
- Candlesticks: OHLC data for events and markets
- Live Data: Real-time milestone information
- Series: Series templates and metadata
- Utilities: Outcome mints, filtering, tags, and search
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dflow-mcp CLAUDE.md is an instructions file published in the GitHub repository openSVM/dflow-mcp (7 stars, last pushed 9mo ago), licensed Unlicense. It adds 1,092 tokens to every session, about $0.0055 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
