DraftCall MCP Server

NFL fantasy football data for the 2026 season, over the Model Context Protocol.

Endpoint: https://draftcall.io/mcp Transport: streamable HTTP, stateless Auth: none. Free, read-only, no API key, no account. Docs: https://draftcall.io/mcp-server/

Ask an MCP-connected assistant "should I start Bijan Robinson or Jahmyr Gibbs in PPR" and it can answer from live data instead of guessing. Every tool result carries the draftcall.io URL the numbers came from, so answers stay citable.

Connect

Any client that accepts a remote MCP endpoint. No install, no clone.

Claude Code

Clients that only speak stdio

Some clients and registries cannot take a remote URL and require a command they can run locally. For those, this repository ships a stdio bridge: it forwards newline-delimited JSON-RPC to the same hosted endpoint, so the tools, prompts and resources are identical and there is still only one server implementation.

docker build -t draftcall-mcp .
docker run --rm -i draftcall-mcp

Or without Docker, using any Node 18 or newer:

node stdio-proxy.mjs

The bridge has no dependencies and holds no state. Set DRAFTCALL_MCP_URL to point it somewhere other than production. Prefer the remote URL above wherever your client supports it; the bridge is a compatibility shim, not the main path.

Tools

Nine, all read-only. Nothing here can modify a league, a roster, or an account.

Prompts and resources

Three prompts, for clients that surface them in a picker or slash menu: start_sit, draft_pick, and bye_planning. Each one names the exact tools to call and the order to call them.

One resource, draftcall://methodology, a single markdown page describing how every derived figure is computed: season basis, scoring formats, tiers, scarcity, opponent difficulty, and strength of schedule.

scoring_format accepts PPR, half-PPR and standard. position accepts QB, RB, WR, TE, FLEX, K and DEF. week accepts 1 through 18.

Data

Player names and statistics are public-domain factual data. Rankings refresh daily. Every figure is labelled inline with the season it describes (2025 regular-season production until the 2026 season accrues a usable sample), and every response carries a stats_season field, so a model cannot mistake a completed season for a projection. DraftCall publishes no projections, ADP, or injury status through this server.
