WHAT IT DOES

What get_latex_structure does on Meridian

AI agents call get_latex_structure to retrieve information from Meridian without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`source`	string	—	Raw LaTeX source, as an alternative to file_path. Ignored when file_path is given.
`file_path`	string	—	Path to a server-accessible .tex file. A sibling .bib referenced by \bibliography is resolved relative to it.

Parameters from the server's own tool schema.

RISK

Why get_latex_structure is rated Low

This tool retrieves and analyzes structural metadata from LaTeX source files using server-side parsing. It returns information (headings, bibliography, file references) without modifying data, executing code, or triggering external side effects. This is a pure read/query operation with no destructive, executable, or financial implications.

From the tool's definition parse a LaTeX (.tex) source's structure WITHOUT a PDF intermediary... returns heading_count, an ordered headings outline... plus unexpanded_inputs... and a bibliography list. No modifications, deletions, or external executions mentioned.

RECOMMENDED RULE

The rule that runs get_latex_structure safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Meridian, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_latex_structure, this is the rule to start with:

get_latex_structure Allowed

get_latex_structure is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_latex_structure": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Meridian, apply this rule, and every get_latex_structure call is checked against it from then on.

FAQ

Questions about get_latex_structure

What does the get_latex_structure tool do? +

[SUPPORT] 106118cd — parse a LaTeX (.tex) source's structure WITHOUT a PDF intermediary. Meridian parses the .tex server-side with pylatexenc (pure-Python, no LaTeX install) and returns heading_count, an ordered headings outline and a nested tree of \part/\chapter/\section/\subsection/\subsubsection/\paragraph (level, kind, text, children), plus unexpanded_inputs (\input/\include filenames, not expanded) and a bibliography list (thebibliography \bibitem entries, and \bibliography{...} + a sibling .bib when a path is given). Pass file_path to a server-accessible .tex, OR pass source with the raw LaTeX inline. Malformed LaTeX returns a partial/empty result, never an error crash. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata are sent to and stored in Meridian's service; self-hosted deployments keep them in the configured local SQLite/Postgres database. This data is visible in the dashboard/API and later project context or handoffs. Delete individual tasks, notes, or decisions where supported, or delete the project/account using the documented controls. Do not include secrets. It is categorised as a Read tool in the Meridian MCP Server, which means it retrieves data without modifying state.

What parameters does get_latex_structure accept? +

get_latex_structure accepts 2 parameters: source, file_path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on get_latex_structure? +

Register the Meridian MCP server in PolicyLayer and add a rule for get_latex_structure: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Meridian. Nothing to install.

What risk level is get_latex_structure? +

get_latex_structure is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_latex_structure? +

Yes. Add a rate_limit block to the get_latex_structure rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block get_latex_structure completely? +

Set action: deny in the PolicyLayer policy for get_latex_structure. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides get_latex_structure? +

get_latex_structure is provided by the Meridian MCP server (@meridianmcp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
