Registry code: 31d9cbb79d90e637
OpenCancer is a cancer patient expert: plain-language, guideline-grounded education for patients and caregivers, recruiting clinical trials, and a path to a human expert review. Tools: ask_opencancer answers cancer questions (diagnosis, staging, treatment options, side effects, tests, questions for the oncologist) grounded in NCCN Guidelines for Patients and medical literature, with sources. find_clinical_trials lists recruiting trials for a cancer type near a place; get_trial_details explains one trial (who can join, sites, contacts). open_case returns a link to start an expert case review.…

- 5 tools: send_feedback, ask_opencancer, find_clinical_trials, get_trial_details, open_case.
- Is opencancer safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
open_case open 1h ago
Give the user a link to start an expert review of their case by OpenCancer and Cancer Commons scientists (records, options, trial shortlist, next step). WHEN TO USE: the user wants a human expert, a second opinion, a trial shortlist built for their exact case, or help deciding a next step. NOT FOR: emergencies (tell them to call 911 or their care team). Returns an intake link only: it creates no case and sends no records. The patient enters their own details and personally confirms consent on that page. Do not pass names, contact details, or records.
{ "type": "object", "properties": { "question": { "type": "string", "maxLength": 500, "description": "Optional: what the patient wants experts to look at, without personal identifiers." }, "cancer_type": { "type": "string", "maxLength": 160, "description": "Optional cancer type, e.g. \"prostate cancer\"." }, "preferred_destinations": { "type": "array", "items": { "enum": [ "cancer_commons", "vivantx", "palitra" ], "type": "string" }, "uniqueItems": true } }, "additionalProperties": false }arguments 28 linessend_feedback unknown never probed
Flags an OpenCancer answer for human expert review, or sends feedback to the OpenCancer team. Used when the user says an OpenCancer answer was wrong, unsafe, or incomplete, or wants to tell OpenCancer something (answer_id identifies the answer; message holds the user's words). Also used to report that an OpenCancer tool returned no usable answer (kind "missing_answer" with answer_id or tool, no message). Feedback is read by the OpenCancer team; it is not an urgent-care channel and no reply is sent through it.
{ "type": "object", "required": [ "kind" ], "properties": { "kind": { "enum": [ "wrong_or_unsafe", "missing_answer", "bug", "idea", "praise" ], "type": "string", "description": "wrong_or_unsafe, missing_answer, bug, idea, or praise." }, "tool": { "enum": [ "ask_opencancer", "find_clinical_trials", "get_trial_details", "open_case" ], "type": "string", "description": "Optional. Which OpenCancer tool this is about." }, "message": { "type": "string", "maxLength": 500, "description": "Optional. The user's feedback in their own words. Contact details are not accepted." }, "answer_id": { "type": "string", "maxLength": 64, "description": "Optional. The answer_id returned by ask_opencancer." } }, "additionalProperties": false }arguments 40 linesask_opencancer unknown 1h ago
Answer a cancer patient or caregiver question in plain language, grounded in NCCN Guidelines for Patients and medical literature, with sources and a link to OpenCancer's care team. WHEN TO USE: questions about a specific cancer: what a diagnosis, stage, biomarker, or test result means; treatment options and what guidelines recommend; side effects and how to manage them; what to ask the oncologist; second opinions; living with cancer. Write the question in the user's language; the answer comes back in it. NOT FOR: emergencies (tell the user to call 911 or their care team now), prognosis or life-expectancy estimates, decisions about a specific person's treatment, or non-cancer topics. Do not include names, contact details, or record numbers. Some questions return a safety message instead of an answer; pass it on as written.
{ "type": "object", "required": [ "question" ], "properties": { "context": { "type": "string", "maxLength": 500, "description": "Optional general context such as stage or treatments tried, e.g. \"stage 3, finished FOLFOX\". No identifiers." }, "question": { "type": "string", "maxLength": 2000, "description": "The question in plain language, in the user's language, without personal identifiers." }, "cancer_type": { "type": "string", "maxLength": 160, "description": "Optional cancer type, to focus the guidelines used, e.g. \"colon cancer\"." } }, "additionalProperties": false }arguments 24 linesfind_clinical_trials unknown 1h ago
Find clinical trials that are recruiting now for a cancer type, near a place, from ClinicalTrials.gov. WHEN TO USE: the user asks about clinical trials, new or experimental treatments, or options after standard treatment stopped working, for a specific cancer. Pass the condition in English medical terms (e.g. "glioblastoma", "HER2-positive breast cancer") and, if known, a city, state, or country. NOT FOR: eligibility decisions for a specific person (only their oncologist or the trial team can decide); general questions (use ask_opencancer). Returns up to 8 trials with phase, nearest sites, and a link.
{ "type": "object", "required": [ "condition" ], "properties": { "phase": { "enum": [ "1", "2", "3", "4" ], "type": "string", "description": "Optional trial phase." }, "keyword": { "type": "string", "maxLength": 120, "description": "Optional biomarker, drug, or treatment, e.g. \"KRAS G12C\" or \"CAR-T\"." }, "location": { "type": "string", "maxLength": 120, "description": "Optional city, state, or country, e.g. \"Boston\" or \"Germany\". Never a street address." }, "condition": { "type": "string", "maxLength": 160, "description": "Cancer type or condition, e.g. \"pancreatic cancer\"." } }, "additionalProperties": false }arguments 34 linesget_trial_details unknown never probed
Get one clinical trial from ClinicalTrials.gov by its NCT number: what it tests, who can join (inclusion and exclusion criteria, original wording), recruiting sites, contacts, and when the registry was last updated. WHEN TO USE: the user asks about a specific trial (an NCT number from find_clinical_trials, their doctor, or a search), wants to know if they might qualify, or how to contact the study. Explain the criteria in plain words and suggest questions to ask the study team. NOT FOR: telling someone they are eligible (only the study team can confirm), or searching for trials (use find_clinical_trials).
{ "type": "object", "required": [ "nct_id" ], "properties": { "nct_id": { "type": "string", "pattern": "^NCT[0-9]{8}$", "description": "ClinicalTrials.gov ID, e.g. \"NCT05902169\"." } }, "additionalProperties": false }arguments 14 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id31d9cbb79d90e637.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/31d9cbb79d90e637/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
