Body Lab MCP server

Connect Claude, ChatGPT, or any assistant that speaks the Model Context Protocol to your Body Lab training. Ask what to do today and why, how last week went, whether you're recovered, or what your squat has been doing, and the answers come from your own data and Body Lab's engine.

https://bodylab.lol/mcp

This repository is the public home of the server: how to connect, the tool reference, the MCP Registry entry, and a Claude Code plugin. The server itself runs at the address above. It's hosted, so there's nothing to install or run.

Connect

You need a Body Lab account. The first time an assistant connects, it sends you to Body Lab to sign in and approve it.

Body Lab isn't listed in assistants' app directories yet, so you add it by its address.

Claude (web, desktop, mobile):

  1. On claude.ai or in Claude Desktop, open Customize → Connectors.
  2. Press +, choose Add custom connector, paste https://bodylab.lol/mcp and press Add.
  3. Press Connect, then sign in to Body Lab and allow Claude.
  4. In a chat, turn Body Lab on from + → Connectors. It's then available in the Claude mobile app too.

On a Team or Enterprise plan, an organization owner adds it first (Organization settings → Connectors). The free plan allows one custom connector. See Anthropic's custom connector guide.

ChatGPT (web; Plus, Pro, Business, Enterprise or Education):

  1. Open Settings → Security and login and turn on Developer mode.
  2. Open Plugins, press +, and create an app with https://bodylab.lol/mcp, using OAuth.
  3. Sign in to Body Lab and allow ChatGPT.
  4. In a chat, choose Body Lab from Developer mode in the message box.

See OpenAI's developer mode guide.

Claude Code:

sh
claude mcp add --transport http body-lab https://bodylab.lol/mcp

Then run /mcp inside Claude Code and choose Body Lab to sign in. Or install the plugin, which adds the server and skills for using it well:

sh
/plugin marketplace add bodylab-lol/mcp
/plugin install body-lab@bodylab-lol

VS Code, Cursor and other clients: add a remote (Streamable HTTP) MCP server with the URL https://bodylab.lol/mcp. For clients configured with JSON:

json
{
  "mcpServers": {
    "body-lab": { "type": "http", "url": "https://bodylab.lol/mcp" }
  }
}

What it can do

An assistant can see your training. With your permission it can also tell Body Lab about today, put sessions you've arranged on your calendar and take them off again, add races and goals at priority B or C, see your lab results and add new ones, for example from a PDF or photo of a lab report, and do the same with body composition scans such as DEXA. It can't change your training history, delete anything, or make an event the A race your plan is built around — that's yours to do in Body Lab.

ToolFor
get_todayToday's (and tomorrow's) prescribed session, the reasons behind it, alternatives, readiness
set_today_contextTells Body Lab how long you have today, what equipment is to hand and which sports are out, and returns the re-prescribed session. Today only. Needs today:write
get_weekThe next seven days as the engine projects them: detailed through tomorrow, summarised after, and shifting each morning
schedule_sessionPuts a session you've arranged — a club ride, a run with a friend — on your calendar, one entry per occurrence, so Body Lab plans the week around it. The same session twice is stored once. Needs schedule:write
withdraw_sessionTakes a session you arranged off the calendar again. It's kept and marked withdrawn, never deleted; Body Lab's own sessions can't be touched. Needs schedule:write
schedule_eventAdds a race or goal at priority B or C. It refuses to add an A event, and can't edit one: both are yours to do in Body Lab. Needs events:write
remove_eventTakes off a race it added itself, after reading it back to you. It can't remove one you entered, and can't remove an A race even if it added it — promoting a race to A is your decision, so taking it back is too. Removing is permanent. Needs events:write
get_weekly_reviewHow a complete week went against what was prescribed, load against the band, the strength floor, and whether training so far supports an upcoming event
get_training_statusFitness, fatigue, form, workload ratio, strain, intensity balance, week by week
list_activities, get_activityYour activities, and one in detail with load, zones, power bests and plan adherence
get_recoveryMorning resting HR, HRV, sleep and energy scores
get_strengthThe strength session Body Lab would prescribe now, estimated maxes, recent sessions
get_profileHeart-rate anchors, FTP, weight, most recent blood pressure, strength equipment, test results, power curve
find_exercisesThe strength exercise catalogue
suggest_routesRoutes you've done before that fit today's session
get_lab_resultsYour blood test results: each marker over time against the lab's range and guideline limits, and whether a change is beyond normal variation. Needs labs:read
record_lab_resultsAdds a blood draw and its results as the report prints them, after the assistant checks the values with you. It can't edit or delete results. Needs labs:write
get_body_compositionYour body composition scans: total and regional fat, lean and bone mass, body fat percent, visceral fat, and whole-body bone density, as your report gave them. Needs body:read
record_body_compositionAdds one scan as the report prints it, after the assistant reads every value back to you. It can't edit or delete scans. Needs body:write

Prompts: What should I do today? (todays-session) and Review my week (weekly-review).

Your data and permissions

Every connection can see your training (training:read). Lab results and body composition scans are separate from it and from each other, and each is off unless you turn it on when you approve an assistant:

ScopeLets the assistant
training:readSee your training, recovery, activities and profile
today:writeTell Body Lab about today: your time, equipment and sports you can't do. It can't change your training history
schedule:writePut sessions on your calendar, and take them off again. It can't change your training history
events:writeAdd and remove races and goals you give it. It can't make one an A race — that rebuilds months of your plan, and you do that in Body Lab
labs:readSee your lab results
labs:writeAdd lab results you give it. It can't change or delete them
body:readSee your body composition scans
body:writeAdd body composition scans you give it. It can't change or delete them

schedule:write covers sessions you've arranged and nothing Body Lab prescribed: a withdrawn session stays on record, marked withdrawn. events:write adds races and goals at B or C only; making one your A race, editing it, or removing it stays in Body Lab, so an assistant can't restructure months of your plan or delete a race by mistake. Every session or event an assistant adds is recorded as that assistant's, and each assistant is held to a rolling limit on how much it can schedule.

An assistant you connected before these existed doesn't get them automatically, and one you allowed for lab results doesn't get body composition. To allow any of them, connect it again (in Claude, disconnect and reconnect Body Lab) and tick those boxes when Body Lab asks. To correct or delete a lab result, to remove a scan, or to change or remove a race, use Body Lab on the web.

Body composition scans, including bone density, are measurements you recorded. Body Lab shows them back to you and nothing more: they are not a diagnosis, a whole-body scan is not a diagnostic bone density test, and nothing Body Lab prescribes reads them.

  • When you approve an assistant, Body Lab shows who published it (or that it's unverified), where it will send you back to, and what it can do.
  • What an assistant reads goes to that assistant's provider, and they handle it under their own terms.
  • See and disconnect assistants any time in Body Lab under Settings → AI assistants. Disconnecting works immediately.
  • Body Lab's recommendations are training guidance, not medical advice.
  • Full details: Privacy Policy and Terms of Service.

For client developers

The server follows the MCP authorization spec (2026-07-28):

  • Protected resource metadata: https://bodylab.lol/.well-known/oauth-protected-resource/mcp
  • Authorization server metadata: https://bodylab.lol/.well-known/oauth-authorization-server
  • Client registration: Client ID Metadata Documents (preferred), or dynamic client registration at /oauth/register.
  • Flow: authorization code with PKCE (S256 only). Include the resource parameter (https://bodylab.lol/mcp). Authorization responses carry iss.
  • Clients: public only (token_endpoint_auth_method: none). Refresh tokens rotate. Revoke at /oauth/revoke.
  • Scopes: training:read (every connection), plus the optional today:write, schedule:write, events:write, labs:read, labs:write, body:read and body:write. A 401 names all eight; the athlete chooses the optional ones on the consent page, and the token response's scope says what was granted. tools/list shows only the tools the grant covers. A tools/call for a tool it doesn't cover gets 403 with WWW-Authenticate: Bearer error="insufficient_scope" and a scope naming the grant's scopes plus the one needed, for step-up authorization.
  • Transport: Streamable HTTP, stateless, on protocol 2026-07-28 and the 2025 initialize handshake.

Registry name: lol.bodylab/body-lab.
