ATP and WTA tennis since 2007: sets, draws, rankings, head to head, surface Elo, sportsbook lines.
Hosted tennis data MCP server giving an assistant ATP and WTA singles results, draws, rankings, head-to-head, surface Elo and sportsbook moneylines since 2007.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.noahowsh%2Facesapi/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}The tennis data API. ATP and WTA singles matches with every set and tiebreak score, tournament draws round by round, player profiles, weekly rankings, head to head, surface splits, our own Elo by surface, and sportsbook moneylines on Grand Slam and Masters / WTA 1000 matches. REST API and MCP server. 500 free credits every month, no card.

Most clients connect to https://mcp.acesapi.com/mcp directly. For a client that launches a local process instead:
It forwards to the hosted server with your key, so every tool and credit cost is the same.
This repo also ships 16 free Claude skills in skills/ that turn Claude into a tennis analyst on top of the tools below: match and player lookup, surface Elo, head to head, ranking history, set-score modeling, odds math, edge detection and backtesting. They call the AcesAPI tools and keep to what the data holds (no serve statistics, moneylines on Slams, Masters and WTA 1000 only).
Or install them as a Claude Code plugin:
Or with the skills CLI: npx skills add noahowsh/acesapi-mcp.
Point Claude at the skills/ folder, add the MCP server (see Quick start), and ask a question such as "who is favored in tomorrow's Shanghai match and why?". Full catalog: skills/README.md. The skills also work on your own CSV or JSON without a key.
The official Python client is on PyPI: acesapi.
Typed errors for a bad key, no credits left, not found and rate limits, automatic retries, and to_dataframe for pandas.
This is a hosted (remote) MCP server over Streamable HTTP. There is nothing to install.

The key can also be sent as an x-api-key header or Authorization: Bearer. Connecting and listing tools works without a key; calling a tool needs one.
REST
Every tool is POST /v1/{tool} with a JSON body.

Add this repo as a Codex plugin marketplace, then install the plugin:
Then open the plugin directory in Codex and install acesapi-skills from the acesapi marketplace. The plugin bundles the skills in skills/ and the AcesAPI MCP server (https://mcp.acesapi.com/mcp). Set your key first (free at https://acesapi.com/signup):
Codex sends it as a bearer token.
The extension adds the AcesAPI MCP server (https://mcp.acesapi.com/mcp) and sends the key in the x-api-key header. Get a free key (500 credits a month) at https://acesapi.com/signup.
