goose Goose LLM cannot use MCP tools, but only MCP resources

Describe the bug

I tried to prompt LLM to use tool, but it seems incapable to use it. This is the conversation I had with goose today. Note that the mcp-wiki extension is taken from https://block.github.io/goose/docs/tutorials/custom-extensions/

─── read_resource | platform ──────────────────────────
extension_name: mcp-wiki
uri: ...


Execution failed: Could not read resource with uri: https://en.wikipedia.org/wiki/T%C3%B4_L%C3%A2m
It seems that the `mcp-wiki` extension was unable to fetch the resource at the given URL. This could be due to limitati
ons on accessing that specific resource from the extension.

If there's anything else you'd like me to assist with regarding this topic or a different approach you'd like me to att
( O)> Use the tool `read_wikipedia_article`

─── search_available_extensions | platform ──────────────────────────



It looks like I currently don't have access to a `read_wikipedia_article` tool, nor can I enable additional extensions 
to provide that capability. However, I can help you in other ways, such as guiding you to access the article directly o
n Wikipedia or perhaps summarizing related information if you're looking for specific details. Let me know!

To Reproduce Steps to reproduce the behavior:

Use the following config.yaml

extensions:
  mcp-wiki:
    args: []
    bundled: null
    cmd: mcp-wiki
    description: null
    enabled: true
    env_keys: []
    envs: {}
    name: mcp-wiki
    timeout: 300
    type: stdio
GOOSE_MODE: auto
GOOSE_MODEL: gpt-4o
GOOSE_PROVIDER: github_copilot

Follow step 1 to step 4 in https://block.github.io/goose/docs/tutorials/custom-extensions/ to create mcp-wiki extension
Open goose and prompt it with "Tell me about Tô Lâm, by using extension mcp-wiki to read this article https://en.wikipedia.org/wiki/T%C3%B4_L%C3%A2m"

Expected behavior It should be able to use tool mcp-wiki Screenshots If applicable, add screenshots to help explain your problem.

Please provide following information:

OS & Arch: Kubuntu 24.04.1
Interface: CLI
Version: 1.0.24
Extensions enabled: mcp-wiki
Provider & Model: Github Copilot GPT-4o

Additional context Add any other context about the problem here.

can you try enabling the developer extension and ask it a simple query to "use shell tool to print the date". i am not sure if the issue here is that the LLM generated incorrect args for the wikipedia URL

@salman1993 The issue here is that it cannot discover ANY TOOLS.

I tried your suggestion and here is the result. brianhuster@brianhuster-ThinkPad-E14-Gen-4:/media/brianhuster/D/Projects/nvim-mcp-server$ goose starting session | provider: github_copilot model: gpt-4o logging to /home/brianhuster/.local/share/goose/sessions/20250530_091708.jsonl working directory: /media/brianhuster/D/Projects/nvim-mcp-server

Goose is running! Enter your instructions, or try asking what goose can do.

( O)> Run shell command to tell me what time and date it is now
