mcp-obsidian
MCP server that interacts with Obsidian via the Obsidian rest API community plugin
Runs with mockssource: GitHubPythonMITcommit 5ee0b84fa831
Python, MIT licensed.
mcp-obsidian runs, with stand-ins for the services it depends on. An Argusic agent installed it in 0.1 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
All 81 unit tests pass, the MCP server responds to initialize and tools/list over stdio, and the Obsidian client makes successful HTTP calls against a mock REST API server.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- under a minute
- Cold machine to finish
- 4 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- uv run pytest passed 81/81; mock REST API integration test exercised list_files_in_vault and search against a real local HTTP server returning correct JSON; MCP stdio protocol responded with valid capabilities to initialize request
- Model tokens used
- 30,249
- Exact commit tested
- 5ee0b84fa831
- Container image
- sha256:cdd920bce783
What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
- Behaviour against real services
- this run was verified against stand-in services only

How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Installed in 0.1 minutes, faster than the median of the 22 comparable projects Argusic has measured.
- Nothing broke on the way: zero errors between clone and running.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
Of the 23 Python projects Argusic has installed and timed, mcp-obsidian was the 1st fastest to reach a running state, and 12 of 23 reached one at all.

[](https://argusic.com/subject/mcp-obsidian)Questions
- Does mcp-obsidian run?
- mcp-obsidian runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 0 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test mcp-obsidian?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 5ee0b84fa831. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test mcp-obsidian?
- The run that produced this verdict cost $0.02: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does mcp-obsidian take to install?
- 0.1 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does mcp-obsidian need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing mcp-obsidian?
- Nothing did, in the recorded run: zero errors between clone and running.
- How does mcp-obsidian compare with the alternatives?
- Of the 23 Python projects Argusic has installed and timed, mcp-obsidian was the 1st fastest to reach a running state, and 12 of 23 reached one at all.
- Where is the evidence for mcp-obsidian?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
