In-path gate · all MCP tools

Using io.github.cyanheads/obsidian-mcp-server in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).

Contracts can change after screening, with no version bump. The gate pins io.github.cyanheads/obsidian-mcp-server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables

OBSIDIAN_API_KEY

required

Bearer token for the Obsidian Local REST API plugin (Settings → Community Plugins → Local REST API).

OBSIDIAN_BASE_URL

Base URL of the Obsidian Local REST API. Default: http://127.0.0.1:27123 (enable "Non-encrypted (HTTP) Server" in plugin settings). Use https://127.0.0.1:27124 for the always-on HTTPS port (self-signed cert; pair with OBSIDIAN_VERIFY_SSL=false).

OBSIDIAN_VERIFY_SSL

Whether to verify the TLS certificate on the Obsidian endpoint. Default false because the plugin uses a self-signed cert.

OBSIDIAN_REQUEST_TIMEOUT_MS

Per-request timeout in milliseconds.

OBSIDIAN_ENABLE_COMMANDS

Opt-in flag for the command-palette pair (obsidian_list_commands + obsidian_execute_command). Off by default — Obsidian commands are opaque and can be destructive.

OBSIDIAN_READ_PATHS

Optional comma-separated vault-relative folder allowlist for reads. Prefix-based with implicit recursion; case-insensitive; trailing slashes normalized. Unset = full vault. Write paths are implicitly readable. Example: 'public/,projects/'.

OBSIDIAN_WRITE_PATHS

Optional comma-separated vault-relative folder allowlist for writes. Same syntax as OBSIDIAN_READ_PATHS. Unset = full vault. Example: 'projects/,scratch/'.

OBSIDIAN_READ_ONLY

Global read-only kill switch. When true, every write is denied regardless of OBSIDIAN_WRITE_PATHS, and the command-palette pair is suppressed (commands can mutate). Useful for shared or public-facing deployments.

OBSIDIAN_OMNISEARCH_URL

Override URL for the Omnisearch plugin HTTP server. Unset derives from OBSIDIAN_BASE_URL host with port 51361. Required only if the Omnisearch plugin is not on the default port.

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

OBSIDIAN_API_KEY

required

Bearer token for the Obsidian Local REST API plugin (Settings → Community Plugins → Local REST API).

OBSIDIAN_BASE_URL

OBSIDIAN_VERIFY_SSL

Whether to verify the TLS certificate on the Obsidian endpoint. Default false because the plugin uses a self-signed cert.

OBSIDIAN_REQUEST_TIMEOUT_MS

Per-request timeout in milliseconds.

OBSIDIAN_ENABLE_COMMANDS

Opt-in flag for the command-palette pair (obsidian_list_commands + obsidian_execute_command). Off by default — Obsidian commands are opaque and can be destructive.

OBSIDIAN_READ_PATHS

OBSIDIAN_WRITE_PATHS

Optional comma-separated vault-relative folder allowlist for writes. Same syntax as OBSIDIAN_READ_PATHS. Unset = full vault. Example: 'projects/,scratch/'.

OBSIDIAN_READ_ONLY

OBSIDIAN_OMNISEARCH_URL

Override URL for the Omnisearch plugin HTTP server. Unset derives from OBSIDIAN_BASE_URL host with port 51361. Required only if the Omnisearch plugin is not on the default port.

MCP_HTTP_HOST

The hostname for the HTTP server.

MCP_HTTP_PORT

The port to run the HTTP server on.

MCP_HTTP_ENDPOINT_PATH

The endpoint path for the MCP server.

MCP_AUTH_MODE

Authentication mode to use: 'none', 'jwt', or 'oauth'.

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 960,209). Verify it yourself.
