使用说明
生物TcgaMcp
目的：使用TCGA分析工具演示MCP服务器
安装了此软件包并在以下位置安装了合适的配置文件 ~/.config/mcptools/config.json
这包括
{
"mcpServers": {
"r-mcptools": {
"command": "Rscript",
"args": ["-e", "mcptools::mcp_server()"]
},
"r-btw": {
"command": "Rscript",
"args": ["-e", "btw::btw_mcp_server()"]
},
"r-tcga": {
"command": "Rscript",
"args": ["-e", "biocTcgaMcp::btcga_mcp_server()"]
}
}
}
然后
library(ellmer)
ch = chat_openai(model="gpt-4o")
ch$set_tools(mcptools::mcp_tools()) # need biocTcgaMcp 0.0.2 for improved type list tool
cc = type_array(type_object(codes = type_string(description = "TCGA tumor type codes"),
types = type_string(description = "TCGA tumor study names"))
ch$chat_structured("What tumor types are available in TCGA?", type=cc)
应该返回一个data.frame。 chat_structured 不是必需的，但会创造
呼叫R会话中的值。

The Cancer Genome Atlas (TCGA) was a large-scale project aimed at cataloging genetic mutations responsible for
different types of cancer using genome sequencing and bioinformatics. TCGA studied a wide variety of tumor types,
including but not limited to:
1. **Breast Invasive Carcinoma (BRCA)**
2. **Lung Adenocarcinoma (LUAD)**
3. **Lung Squamous Cell Carcinoma (LUSC)**
4. **Prostate Adenocarcinoma (PRAD)**
5. **Kidney Renal Clear Cell Carcinoma (KIRC)**
6. **Thyroid Carcinoma (THCA)**
7. **Stomach Adenocarcinoma (STAD)**
8. **Liver Hepatocellular Carcinoma (LIHC)**
9. **Colorectal Adenocarcinoma (COADREAD)**
10. **Brain Lower Grade Glioma (LGG)**
11. **Glioblastoma Multiforme (GBM)**
12. **Ovarian Serous Cystadenocarcinoma (OV)**
13. **Pancreatic Adenocarcinoma (PAAD)**
14. **Bladder Urothelial Carcinoma (BLCA)**
15. **Head and Neck Squamous Cell Carcinoma (HNSC)**
16. **Uterine Corpus Endometrial Carcinoma (UCEC)**
17. **Skin Cutaneous Melanoma (SKCM)**
18. **Esophageal Carcinoma (ESCA)**
19. **Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (CESC)**
20. **Acute Myeloid Leukemia (LAML)**
21. **Kidney Renal Papillary Cell Carcinoma (KIRP)**
22. **Kidney Chromophobe (KICH)**
23. **Uveal Melanoma (UVM)**
24. **Mesothelioma (MESO)**
25. **Pheochromocytoma and Paraganglioma (PCPG)**
26. **Thymoma (THYM)**
27. **Adrenocortical Carcinoma (ACC)**
28. **Cholangiocarcinoma (CHOL)**
These tumor types were selected for their prevalence and mortality rates, as well as their scientific and clinical
importance. The data collected from TCGA has been crucial in advancing the understanding of the genomic underpinnings
of cancer.
这并不太令人满意，因为我们知道有33种肿瘤类型。
